I'm helping my little brother build a cheap gaming PC, but I don't know if these are the best parts for the price or if they are compatable. Right now it will cost $545 for the PC w/ vista and a 19" moniter.

AMD Athlon 64 X2 7750 Kuma 2.7GHz (w free game)

HIS Radeon HD 4670 IceQ Turbo 512MB (w free game) :D

GIGABYTE GA-MA770-UD3 + Rosewill Mid Tower Computer Case with 350w PSU combo

G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 1066 (PC2 8500)

LG Black bezel 16X DVD-ROM 52X

Western Digital 320GB Hard Drive + Windows Vista Home 32 bit combo

Acer 19" Widescreen Moniter

Any suggestions or help are appreciated, than you.

ok i changed the PSU to the chearper one and the video card to the Saphire. and you say 450 W is enough to power it? can anyone second that?
