sup guys well actually i have a 5870 crossfire in my pc right now and i wanna upgrade it so im thinking about buying another 5870 to do a tri fire configuration but does it worth? maybe its better to buy idk 2 gtx 580 to put them in sli? i wanna upgrade my gpu cuz i love to play all my games at max settings and when i play a really intense game like crysis 2 sometimes it lags, not too much but it really annoys me .
system specs:
cpu: core i7 920 d0 oc @ 4.2ghz 1.3v stable
gpu: 2 his hd 5870 in crossfire x oc @ 910mhz/1250mhz
mobo: asus rampage III extreme (upgraded from a asus p6t deluxe v2)
ram: supertalent 12gb ddr3 6x2gb @ 1603mhz 1.64v
hdd: 2 western digital velociraptors 300gb in raid 0
so what do you think guys another 5870 or maybe 2 gtx 580 or 2 6970?
