Get the 2GB edition MSI twinFrozr ii, BF3 even on 720p uses 1.35GB ram on my pc. I'm sure future gams will ustilise more RAM also.
Also it is OCd slightly and if you change the up the voltage you can get considerably higher frames than a stock 570.
The temps are excellent at the standard frequency, not exceeding 65c on prolonged gaming.
Sigh. I can't find the 2GB version on newegg in Canada.
Actually, I just saw pre-order prices...
$240 EUR = $334 CAD?
