I am planning to buy a 2nd hand or maybe brand new 6950 to crossfire with my 6950 twin frozr iii. Would it be worth it or should I upgrade to the new generation of cards by selling my current card? My budget will only be £240 (after selling my 6950).
Also would my XFX XXX Edition 650W be enough to crossfire both cards? My CPU i5 2500k is at stock settings and plan to keep the cards at stock settings as I have no time to overclock.
