I have the XPS 8300 with an Intel Core i7-2600 and a Nvidia Geforce GT 530 right now and I'm looking to upgrade so I can play Battlefield 4. After quite a bit of research, I'm looking to get a EVGA Geforce GTX 660 3GB FTW SIGNATURE2 and a Corsair TX650 V2 and I just wanted to make sure everything was compatible and if I would need a new case and/or more cooling. Any input would be appreciated. Here are the links.
If you are gaming at 1920x1080 or lower rez, you won't ever dip into the 3rd gigabyte. And the Gigabyte card has a slightly faster clock speed. You won't go wrong with either card, tho. Unless you are one of the unlucky few that get a DOA card. Doesn't happen often, but it does happen.
