I recently received the HP s5610f Slimline for Christmas.. too bad my family doesn't understand why gaming computers are build the way they are xD So I am also interested in replacing the graphics card on my rig, and I guess [if I must] replace the power supply as well. I have a similar budget to jks279 so any info you all could give would be extremely helpful. :]
By the way I play games like Battlefield: Bad Company 2 [which barely even runs with the ATI Radeon HD 3000], S.T.A.L.K.E.R., and Batman: Arkham Asylum to name a few.. and it pains me to see those games in such low quality, because I know they can look amazing. >_<
