Hello all, new user and what not. I'm not too familiar with hardware, and I've done countless research, but I always seem to second guess myself. I don't want to buy something if it turns out to be crap, and I find out I could have bought something better for 4-5 dollars more.
Anyway, onto my question. My current CPU is a AMD Athlon 64 x2. Not sure of the model, sure I could look it up easily. Here is some more info about my current pc. Keep in mind, this was not built for gaming. I'm adding parts to it as I go. I'd also prefer AMD, as Intel is a bit out of my range in terms of affordability. Especially since I'd need to buy a new MB as well.
HD: 500 GB (Again, not sure of the exact model)
GPU: EVGA SuperClocked GeForce GTX 550 Ti 1GB
PSU: 650 W
Case: Dell Inspiron 519 Case (ATX Micro MB)
Now, I know, it's no gaming build. It runs most games on medium with lag, of course. What I'm looking for, is of course upgrading my CPU. I know it will be a big upgrade, but just looking to see how it would perform with games like Tera, Crysis 2, and..pretty much any modern game.
Any help is much, much appreciated.
EDIT: Oh, and just for the record I don't have much to spend. My limit is $180-$190
