Hi, I am planning on buying a second graphics card for my computer for 2 reasons

- Better gaming performance
- Dual monitor setup
My Current Graphics card - 1GB AMD RADEON™ HD6450 - DVI,HDMI,VGA - DX® 11
The Graphics card I want to buy - AMD RADEON™ HD7750

I need to know if I buy the second graphics that it will work in my computer and work together with the other graphics card at the same time to get better performance. I also need to know if my PSU will be able to power this.

Here are my other specs:
Processor: AMD A8-3870K APU (3.0GHz, 4 Cores) & AMD Radeon™ HD 6550D Graphics
Motherboard: ASUS® F1A75-M: FM1 A-SERIES, SATA 6.0GB/s, USB 3.0
RAM: 8GB SAMSUNG DUAL-DDR3 1333MHz (2 X 4GB)
Memory: 500GB SATA-II 3-Gb/s HARD DRIVE WITH 16MB CACHE (7,200rpm)

POWER SUPPLY: 450W Quiet 80 PLUS Dual Rail PSU + 120mm Case Fan

Can my computer take both of these cards, Can it power them and will they both work together and allow me to set up 2 Monitors?

Thanks in advance!

The 6450 will not work with the 7750 as far as getting extra performance. You can use the 2nd card to drive a different a 2nd monitor but the 7750 should be more than capable of doing that all by itself.

Take out the 6450 and install the 7750 and you will be good.

I would save up a card like a 7770. As you wouldnt gain any performance improvements if there not SLi/Crossfire. The only thing you would be able to do is have it as a dedicated physx. Which is a Nvidia thing but works with AMD. The best thing to do is buy one card thats better than both. Like I said nothing will increase if their not Xfire'd.

I've decided to re-post my problem in the form of buying a new graphics card that will replace my old one completely, thanks for all the help though :)
