I was going to buy a two 1gb GTX 460's for $230 each by gigabyte, or I could get two 2gb GTX 460's for $260 each by Palit. I need two cards b/c i plan on using 3 monitors while gaming. is it worth it to shell out the extra $60 for the 2gb versions?
you need two GPU's w/ Nvidia to support three monitors. with ATI you only need one 5xxx series card, but will most likely have to buy a Display port adapter (Which goes for $100 on average) to run three monitors.
I personally think nvidia is better, considering two GTX 460's slightly overclocked are comparable to a HD 5970.
Also like i said w/ ATI you have to buy a display port active adapter which runs for $100, or have a monitor that supports display ports. Nvidia also scales much better than ATI so w/ all that in mind I would go w/ Nvidia.
I'm going for one GTX 470 for now, and then couples months from now getting a second 470 and then two more monitors
