Also, I've read reviews that say the monitor is bad for gaming, is this true? It's on sale at £138 around so I really would like it.
Supposedly the 660TI and 670 are supposed to be out in a month and I don't know how accurate my sources are but the speculation is that they're going to be in the $300 - $400 range to compete with the 7870 and 7950, I don't know of any Keppler-based cards that are going to be debuting in the $200 - $300 range yet.
They will be better than the 5xx series. This has already been proven by the GTX 680. At full load with two of the GTX 680s, all you need is a 750W PSU. That is 25% LESS power than the previous gen's GTX 580, which required 1000W.
