Hey guys i was just surfing a site with people selling their older stuff and managed to buy a i7 2600k for just 130 euros.. now theres another deal thats pretty nice aswell.. either 2 x msi HD7850 twin frozr for 330 (maybe 300) or 2 x XFX HD6970 for 360 euros or 2 x msi GTX 560 ti frozr for 320 or 2 x EVGA 560 ti superclocked for 300

which should be the best deal? there's a bunch more for sale but those are all single cards.. 580's for 250/275 also a 660 and 670 for 300 euros.. and a 680 for 385..

theyre all nice, which should i take
