Advice on Graphics Cards

[Abriael]

Still the cpu bottleneck is a valid point. That is going to cause a large drop in fps.
Not a hypothetical drop, a very real, large drop.
My system with that cpu, would loose about 4k points in the benchmark, on estimate.

Bottom line. The gpu is going to give you the most increase in fps, at the least overall cost.
You would need to entirely rebuild the system, to remove bottlenecking.
The mobo, cpu and memory would need to be replaced, to make as much difference as the gpu by it's self.

To the OP:

Get one of the GPU's recommended and call it a day, if you are not looking to spend a thousand dollars or more.

It was already brought up. Her mobo doesn't need to be changed. It's an AM3, and as such it supports a 965be which is plenty not to bottleneck a 660. The only problem is the PCI 1.0, but that's just a 5% loss for a 660.

I recently had to upgrade from 4GB cause TERA was using up all my free RAM (it is compiled with LAA, so it can use up to 3GB RAM.. which it does), leading to ugly stuttering and I can only see it happen more often in the future with x64 systems being commonplace now. I was usually advocating 4GB RAM is enough, but with a mere 10€ difference in price, it's safer to go with 8GB for dual channel nowadays.

In my experience it's actually better to have 4GB of good memory (IE: Corsair Dominator for instance) than 8 GB of 10€ memory, to be honest.
