Nexuiz dont support multicore CPU. So if u have for ex a p4 3.0Ghz, change that with a dual core 1.5Ghzx2 is the same to have a single core 1.5Ghz (bad for nexuiz if u want good graphic).
I know help a lot performance have more RAM and maybe change graphic card with a lot of ram dedicated.


Not true, a single core system have to run everything including nexuiz on that core. a multi core setup has more cores to spread the system load (such as the gpu driver load, which can be substantial, etc) on. thus multi core can well be better (and are in fact recommended for any current generation gpu too) then a mono core for Nexuiz. That said i dont know of any gaming capable mono core cpus sold today :P

If your on a tight budget id recommend looking at a AMD Phenom II X2 545 or AMD Athlon II X4 620 based system. If you can spend some more, the Intel core i5 looks nice. System ram would be a minimum of 2gig, personally id go for 6-8. For gpu id suggest the nvidia 9600 gt if your on a tight budget (~50 eur here) or the 9800 gt for midrange (~95 eur) Theres some interesting Ati cards too, but due to their driver problems i would not recommend ati. still if your windows only and likely to stay that way for a long time, it may be worth a look. The rest of the system is preddy much a non issue wrt to gaming. well, maybe snd card, but the built in ones are usually ok these days. oh and make sure you get a good powersupply with enougth output (id guess around 500w for this rig), else your shiny new stuff will be crashing all the time.

I just recently upgraded to a dual-core 2.9 GHz AMD, 2 GB RAM, GeForce 9600 GT system plus a new case. I'm fairly happy with it, you wouldn't believe the difference it makes when you can play with 300 FPS vs 30 FPS. :P The cost was around 250 EUR (including only a video card, processor, system board, memory and case + bundled 450W PSU). By going for an Intel instead and thus a cheaper system board as well, I believe it's possible to fit into a 200 EUR budget.

Nexuiz dont support multicore: not true?
my example about running Nexuiz on dual 1.5Ghz instead a single core 3.0Ghz: not true?

Well my experience is that. I have now a dual 1.6Ghz instead my previous p4 3.2Ghz and nexuiz run with half or less frame rate and now if i want have a decent frame rate i have to set graphics to low value. But i can render with Blender 5% faster now for ex. Is true!
I have compared a single core and the 'equivalent' dual. I not said all dual core are bad for Nexuiz :)

Intel has a nice and affordable CPU called Pentium Dual Core E6300 (no, not the Core2Duo E6300!!) at the moment. It's running at 2.8GHz default, and you can easily OC it to at least 3.6GHz if you really need it. From GBP 56 up. Moster bang for buck than phenoms, definately :)

This is a nice one.

Depends on what the current bottleneck of you system is giuseppe, however since nexuiz is not the only thing running on the system the other core/s of a multi core system is not idle. And thus more cores can still help performance even if nexuiz itself just uses the one thread. So no, 2x 1.5 ghz is not the same for nexuiz as 1x 1.5.

Oh, and comparing Mhz to Mhz across different cpu architectures is pointless these days ;)

if your new 1.6 ghz (c2d i assume) is running nexuiz at half fps compared to a (p4?) of 3.2 ghz at otherwise comparable hardware, theres proly something wrong with your puter (and +5% blender render speed sounds to little too). The c2d (and just abt every other modern performance directed cpu architecture) get much more done per mhz then the p4 arc does.

from here

http://en.wikipedia.org/wiki/Dual-core

The amount of performance gained by the use of a multi-core processor is strongly dependent on the software algorithms and implementation.
...
In addition to operating system (OS) support, adjustments to existing software are required to maximize utilization of the computing resources provided by multi-core processors. Also, the ability of multi-core processors to increase application performance depends on the use of multiple threads within applications.
...
Two processing cores sharing the same system bus and memory bandwidth limits the real-world performance advantage.


So multi core tecnology is much better single core but needs appropriate 'software algorithms and implementation' that use 'multiple threads' and needs appropriate hw components.
__________

And from here
http://compreviews.about.com/od/cpus/a/dualcore.htm

Most of the early dual-core processors are going to be running at lower clock speeds compared to single core processors. The rational behind it is that a dual-core processor with each running at 1GHz should be equivalent to a single processor running at 2GBz. The problem is that this doesn't work in practice when the applications are not written to take advantage of the multiple processors. Until the software is written this way, unthreaded applications will run faster on a single processor than a dual-core CPU.


So a dual core 2.50-3.00 Ghz x 2 is good for nexuiz but my 1.50 Ghz x 2 i dont think (sure with a good graphic card with a lot of ram yes). The fact is Nexuiz cant take the great advantage of multi thread. And is a pity.
_________

Sorry k0jak im OT


[edit: i correct my info]
-my old CPU was a pentium HT 3.20Ghz, my new is a pentium dual 1.60 Ghz x2
-now i can have with blender render 50% faster (just controlled my old renders)

Hmm you either miss my point or ignore it ;) anyways, lets stop threadjacking.

400 british pounds, so that's about 400 Euros.

Building on the cheap eh? Alright here's what I found so far, I'm still working on it though because it's about 25 pounds over budget. I strictly used UK sites only and because I don't know what the hell it is I included the prices with VAT. I'm going to see if I can shave the price down a bit without sacrificing the specs (256 bit VGA, and 3GHz Phenom II are a must) too badly. There were only two sites used to piece this list together and this only includes the tower with no peripherals, software, or monitor. This also doesn't include shipping, but once again I only navigated two retailers to minimize the costs there.


Price
-------------
Budget: £400 British Pounds = €437 Euro = $650 USD

Total with VAT (whatever the hell that is): £424.46 British Pounds

£34.29
http://www.ukpcparts.com/product/ASR-N68PV-GS.htm

CPU AM3 (AM3 CPUs are backwards compatible with AM2+ socket)
AMD Phenom II X2 (dual core) 3.1GHz
