Merry Christmas to you

I do think a GTX 660ti will be bottlenecked some by an Athlon II X2. Sure, it'll perform better than your 5770, but I don't think you'll get everything it has to offer performance wise. I don't think I'd go any higher up than the GTX 650.

First of all, I wouldn't bother adding a GTX 650 to one of your upgrade choices as it's not much better then your HD5770. Your Athlon CPU will definitely be a bottleneck for the GTX 660 Ti so if I were you I would start looking around for a new CPU, an overclocked Phenom 2 x4 955 or anything higher should be sufficient for that GPU :toast:

Isn't it possible to unlock those to a 4x athlon?

Won't matter much in the grand scheme of things. That CPU architecture is rather old these days.

Merry Christmas!

I think unlocking to quad core can help to some extent, especially for games that support multi-threading.

And I guess you may have more luck with AMD GPUs. I found this interesting article by Hardwareinfo about CPU scaling, GPUs and the respective drivers for AMD and Nvidia's GPU, in this case a HD 7970 and GTX 680 have been tested with 10 different processors. The article says that the AMD HD 7970 in general performs better with a relatively lower performance CPU than the GTX 680 does (as several tests have shown that the bottlenecks with the HD 7970 are relatively smaller). Hardwareinfo thinks it may have something to with driver overhead.
