Hi, after buying my 8800GT last Christmas i'm up for an upgrade, especially since Crysis Warhead has come out!
I have the option to buy another 8800GT and put the two in SLI mode which i assume will give me twice as much power for most games?
Are there any recently released or up and coming cards from Nvidia or ATI which will give me better performance than 2 8800GT's, if so by how much?
I don't mind waiting a few months for something new if it gives me say, 3X the performance of a 8800GT. My budget is around £200.
As you can guess i am a little out of touch with recent developments!
Thanks.
