Thanks!, DO you think ill do well in gaming? like 1080p modern games at like 50-60 fps? thats my aim for this pc
Probably can be done. Maybe not at max but there's one thing for certain that the more settings you turn on in the game, the less your CPU matters and the more the GPU matters. Not to say the CPU becomes irrelevant, but when people talk about CPU limited you aren't CPU limited when you start adding AA and such.
I had a 3.8Ghz Q9950 with 8GB DDR2 @ 896 and a single overclocked GTX 670 at one point. Here's a few benchmarks I did. As you can see it is entirely possible depending on the game to get 50-60fps averages. You may have to turn off AA or a few settings like shadows etc to hold that number depending on the game. Your 3770 is much faster than my Q9550 is even with 400Mhz less. A 7950 overclocked matches or beats an overclocked GTX 670 as well. So I think your system would do better than my results below. An SSD does not help fps but it does help with loading times and general OS tasks so I do recommend trying to budget for one as the difference is night and day.
All games are 16xAF 4xAA 1920x1200 with max in game settings except crysis 2 with AA turned off, but I did run with DX11 and High Resolution textures. Batman was run with Physx off.
