So I am finalizing my PC parts on Newegg and I was wondering what the difference is in performance between these two video cards:
EVGA 02G-P4-2680-KR GeForce GTX 680 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card
EVGA 04G-P4-2686-KR GeForce GTX 680 w/ Backplate 4GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card
Unless I am mistaken, the only difference is the first one has 2GB Memory and the second has 4GB. What kind of performance increase does the extra 2GB provide when I am gaming or just like surfing the web and watching videos or something. There is a $40 price difference so if the result is only a few more Fps with the 4GB I don't think its worth it.
2GB is enough if you are at 1080p, if you are at that 4GB is not needed. If you are above that, then go with the 4GB card. However the 680 is a waste if you are conscious about cash, the 670 does the same thing for $100 less.
Get the EVGA 02G-P4-2680-KR GeForce GTX 680 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card unless you don't mind spending $40 more
The 4GB is only useful on multi monitor high resolution.
For gaming @ 1080p and regular day to day use NO Need 4GB and doesn't increase performance at all.
Edit: As cookybiscuit said going over GTX 670 you will loose a tiny few frames 3-5FPS but can save more
Im using a GTX 670 FTW by EVGA and it surpasses my expectation.
Highly recommended as a alternative to the GTX 680
I ended up going with the GTX 680 4GB w/ Backplate.
I only game at 1080p right now, but I do like to plan for future expandability. My rig is setup for SLI, so down the road if I grab another card I get to use the power of 2x 680's with a 4GB memory cap since SLI doesn't combine memory.
I also mess with user-made graphics mods for games like Skyrim, Crysis, etc from time to time, and some of those can dramatically raise memory use.
