buying a pc very shortly: are these spec good to run crysis on highest?

[Zlejedi]

They are more or less the same in terms of raw power (some games will favour one architecture or the other) but slight edge goes to 260 due to lower power consumption at idle, cuda and physx support (it is marginal but it'sbetter to have it than not) ,896 MBs of ram which sometimes gives nice edge for games with huge textures and more quiet cooler.

But you will be happy with either of those.

PS. Just make sure you get one of the core 216 versions of gtx 260.
