Hey guys I am torn apart between two Graphic Cards right now, I have everything else in place but I do not know which Card I should be buying. What are the two Graphic Cards you may be asking? Well they are the ATI Radeon HD 6850 and the 7770, and I need help deciding which one is the best for my system in the end. My computer Specs are as follows.

Here is my Monitor and my Computer Specs:

Monitor: Acer S211HL bd 22" Class LED Monitor - 12M:1 Contrast Ratio, 5MS response time, 1080P, 1920x1080

OS: Windows 7 64BIT

Tower Case: Diablo Tek Elite ATX Mid Tower (Comes with a 450W PSU but I am switching it out to meet the requirements on my Graphics Card)

Power Supply: Corsair 650TXV2 - 650W, 140mm Fan, Active PFC, 80 Plus Bronze, +12v 1 = 53 A

Processor: AMD Phenom II x6 1045T - Six Core, 6MB L3 Cache, 3MB L2 Cache, 2.70GHz, Socket AM3, 95W, Fan, Retail

Graphics Card: Radeon HD 6850 or 7770 <---- This is where I need help!

MotherBoard: Gigabyte GA-78LMT-S2P

RAM: ADATA 4GB x2 DDR3 (8GB Total)

Hardrive: 1TB Seagate Barracuda

Disc Drive: Lite-On IHAS124-04 Internal DVD Writer


There are my Computer Specs for my Gaming PC that I am building. It will be on for as long as 12 hours a day and maybe even longer. The 6850 is faster and offers a better performance than the 7770, but the 7770 cuts the amount of Watts used in half. In the end I believe I have enough left over Watts from my PSU that it won't matter how many Watts the 6850 is using. Please do some research of your own and help me decide which Graphics Card I should be buying for my computer. If you have other suggestions my budget for the GPU is $150 but I believe these are the best two GPU's for this price range, thanks!

Nothing bad with having too much Wattage is there?

If you want to game at 1080p your going to want at least a 6850. That said I agree the PSU is overkill for your needs. Try to shave a few bucks off the PSU, stick with Corsair, Antec or XFX in the 500w range, 80 plus bronze of course. Then get a 6870 and you'll be able to play at 1080p on higher settings with better frame rates.
 
First of all, very good that you are replacing the Diablotek PSU-shaped object with a real power supply.
The other advice you've gotten is all good. The HD6850 is stronger, the HD7770 uses less power. Either of those would run on a 380W Antec Earthwatts.
If power is notably expensive where you live, you will not "suffer" with the performance of the HD7770; but the HD6850 is not exactly a power hog either.
Neither would be a bad choice; people around here tend to go for stronger parts.
Have you actually bought all the rest of your components?

Yes I have purchased everything besides the Monitor, GPU and PSU. So say I pay the extra $30 for the Radeon HD 6870, what is a good PSU for my Computer Specs that is around the budget of $50-$60?
