We have the sonics in, which to be fair, are fantastic (I have 2 of them in my Rig, so does JakAttack) The Sonic Plats are around 40 quid more i believe, all for being higher than stock overclocked (just so you know my sonics are running at 850 core daily and 2100 Mem in afterburner, but I have had 900 core out of them for extreme benchmarking)
Any way you look at it the 460 is a hell of a card
eh? how many CUDA cores does the 460 have? Kinda forgot. I hope your 460 can't beat my 470 though. I really hope. ;-)
