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

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.
