DEFFO agree with craig, buy a PROPER psu. ive used cheap shite ones for years (i blow one up about every 6 months... lol) and finally got round to getting a proper one and its SOOOO much better.

and if you can get a mobo thats supports your chip AND has a pci-e slot then that would work.

i still think you should sell yours to craig, and take craigs 9800 as thats SO much better thana fx5200 its unreal! i really dont think you'll benefit THAT much from a topspec gfx card on your pc, you dont hav the other goodies to get the most out of it frankly.

also for BF2 i'd deffo reccomend 2GB of memory, the performance on mine with 1GB was quite poor, with 2GB its MUCH better. BF2 is the kinda game that eats up shedloads of memory!
