Hello there,

I'm new to this community and after browsing for about an hour or so, I wanted some advice from you guys.

My computer currently has : Asus M4A88T-M/USB3 (Motherboard)
AMD Athlon II X3 445 @3.1Ghz (Processor)
4GB DDR3 (Ram)
480W (Power Supply)

I was thinking about getting a graphic card, and I made some research on the internet and
I came across two graphic cards that meets my budget :
ATI Radeon HD 7750 and HD 6770

Knowing that my motherboard has PCI Express 2.0, I've just realized that the HD 7750 wouldn't be compatible, since
I can read that it's PCIe 3.0.
Fortunately the HD 6770 uses PCIe 2.0 so I'm thinking about getting it
but I wanted to know your opinion guys.

Thanks for the reply :)

PCI-E is backwards compatible, so you won't have to worry about 3.0 vs 2.0 compatibility :)

Personally, I would take the Radeon HD6770 as it performs slightly better than the 7750.

However, if your budget allows, I would highly recommend the Radeon HD7770.

Radeon 5xxx and 6xxx are 2.1 actually...which has some issues with some motherboards with PCIe 1.x. Your mobo with PCIe 2.0 should be fine with either HD 6770 or HD 7550.

HD 6770 and HD 7750 perform similarly...some games perform better on one or the other. No external connector needed for the HD 7750.

Don'y get 7770 or 7750. you will be spending more money on power efficiency than performance. I suggest you get a 6770 or better a 6850 which is awesome card!

I would normally suggest the same, but my concerns about OP's PSU kicks in. The 7770, 7750, and 6770 all require little power whereas the 6850 will most likely need a PSU upgrade if his 480w is generic.

Yes indeed, i'm not planning on getting a new PSU so I'll probably go for an HD 7770.

Thanks for your advice guys :)
