First off, my rig: Dell OptiPlex 760 MT Intel core 2 duo E8400 3.0Ghz 4 Gb DDR2 800Mhz Ram Corsair CX500 PSU 1920 x 1080 resolution (Win 7 64 premium)
Here are the cards: EVGA 01G-P3-2642-KR GeForce GT 640 Super clocked 1GB 64-bit GDDR5 Link to Newegg: http://
EVGA 02G-P4-2643-KR GeForce GT 640 2GB 128-bit DDR3 Link to Newegg: http://
I'm tempted by the first one for a few reasons: The price (10$ cheaper, budget is TIGHT!), DDR5 (but it's only 64 bit! ARRRGH!) and lastly it's factory Over Clocking - pretty sweet but I can't figure out if that will compensate for 64 bit memory.
The second seems a safe bet but, if there isn't much difference, I'd like to save 10$
This card will be used for gaming to the best of my CPU's abilities

GT 640 DDR5 without a doubt. Its worth extra 10 dollars!
GDDR5 card will always be faster than GDDR3 with the same GPU.
