GPU: More memory or faster clock speed?

[rreluzco]

Hi,
Without going into an entire unnecessary story I'm in a position where I can choose to have either of the following GPU combos to run in SLI:

Option #1
A pair of EVGA SuperClocked 01G-P3-1563-AR GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16
900 MHz clock speed
1800 MHz Shader clock
4212 MHz Effective Memory Clock

OR

Option #2
A pair of EVGA 02G-P3-1568-KR GeForce GTX 560 Ti (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16
822 MHz clock speed
1645 MHz Shader clock
4000 MHz Effective Memory Clock

I run my games at 1920x1080

My system specs:
AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz
ASUS M4N98TD EVO AM3 NVIDIA nForce 980a SLI ATX AMD
G.SKILL Ripjaws X Series 16GB (4 x 4GB) SDRAM DDR3 1600
RAIDMAX RX-1200AE 1200W ATX12V v2.3 / EPS12V SLI Certified
WD Caviar Black 500GB 7200 RPM Hard Drive 3GB SATA
Creative Sound Blaster X-Fi Titanium Fatal1ty Professional
Windows 7 Premium Home Edition 64 bit

I'm a gamer and would love an opinion on which set up would be best for my system. Neither will cost me any more than the other (even thought the 2 gig cards are valued at about $25 more each)

Any help would be greatly appreciated

More memory allows you to run more detail in game especially at higher resolutions. The faster clock will give more raw power with less detail.

Usually I say Yes. You can't tell from looking at one thing which of two different cards will provide better frame rates. Think of a CPU. Which would you rather have, a CPU with a 2.6GHz clock rate or 2MB L2 cache? You really have no idea which would be better.

In this specific case I'd say get the 2GB cards if they are the same price as the 1GB. You can always OC cards and get more clock speed, you can't add ram to the cards. And the less then 80MHz difference between the two shouldn't be much.

Well I received and installed the two 2gig cards at 822mhz from months of using two 1gig cards at 900mhz and the 2g blew them away. In my case what a difference. Metro 2033 had a really big improvement in regards to smoothness. BF3 had a HUGE difference. Wow who knew the extra memory would make such a difference. Thanks again for all the help
