Currently I can spend around HK$10000 which is a bit less than US$1300 and I might geting 8800 ultra sli or maybe gtx depends on availibilty of ultra and so on. If I get sli i have to buy new psu new motherboard that is compatible with sli and also the 2 cards connector which i might not have enough money and probably wil get soon. Please post the prices of each item the lowest prices. Also if I was to get quad core qx6800 will it be better? This means i am upgrading only my cpu and not anything else. Hope you guys can give me good decision.
