Been out of the computer game for a while and am looking to do an upgrade on a system that was given to me.

The mobo is an ASUS M3A78-em with an AMD Phenom 9750 cpu

Money is tight to do this but I need a better video card til I can build be a better system.

So recommendations?

id just get a used 7950 since they are about $100 and its not really worth going above or below that. You can get slower stuff used out there but youll only save a couple bucks to do so. To step up over the 7950 would probably be wasted power given the 9750 phenom I.

If you cant find a 7950, a used 7850 2gb/7870/gtx760/r7 265/r7 270/r7 270x/gtx 670 would be a decent card around 50-75$

Yea....sorry I was a little vague as to budget.....as always as cheap as i can at the moment but the $100-120 range will probably be about my limit right now.

What I was also wondering about was compatibility with this mobo.
I'm still not up to speed with the current standards(My last major vid upgrade was to a gtx 8800 so I drooped out with PCIe x16 as the newest thing) Now there is PCI Express 3.0 x16 and I need a quick catch up on what's new.

Your motherboard supports 1 x PCIe x16 (Support PCIe 2.0)

For comparison purposes, since your budget is $100-120, the fastest card you can possible afford is a used HD7950/HD7970 or 670, etc.

For this level of GPUs, the performance loss between PCIe 2.0 x16 (like your motherboard has) is 0-1% compared to PCIe 3.0 x16:

Going all the way up to a GTX980, it's still only 2% at 1080P:

Your CPU is by far going to be the bottleneck here, not the PCIe 2.0 x16 bus.

So used HD7950/7970 or GTX670/680 or if you want new, GTX750Ti for $110.
