Hi all, I have the following PC: i965 @ 3.8Ghz V10 aircooling 12 GB Dominator GT @ 1866 Mhz SSD agility EX 60 GB EVGA classified VI X58 Bluray Dvd rom Asus Xonar 1.3 HDMI 3 X Monitors DEll 3008 WFP Until now i was running the PC with 2 X Gtx 295(MSI) with no problems. One of the cards is now malfucitning and my store will swap them because they are under warranty. i have now the following choice upgrade to GTX 480 SLI or ATI 5970 Xfire. What is most important for me? I want to have PhysX and a good gaming experience. I am an nvidia fan but definetely Ati consumes less Watt and outputs more frames. My big problem is whether I can have PhysX with ATI cards(by suing nvidia cards or AGEIA). i want to know what you believe. What cards should i get and why? I wouldn't have upgraded if i didn't have the issue with GTX 295 but a decision needs to be made. PROS of ATI 5970 faster than the competition more economical CONS of ATI 5970 no PhysX not good at Antialising as Nvidia(does it matter though?) variances in perfomance Pros of GTX 480 PhysX better scaling at games through SLI Cons of GTX 480 hight Temp not as fast 5970 can you share your view with me?
