I am writing with a build i have on hand. Just asking for possible bottle neck or compatibility issue I will be using the build for some gaming but would like to know the strengths and weaknesses in different uses.
It's pretty weak for everything except generally use. For gaming, you're being held back a lot by the GPU and CPU, depending on the resolution of the monitor. If it's fairly high (like above 1280x), you're being held back a lot by the GPU. If it's at lower resolutions, you're being held back by the CPU.
The CPU is restricting you in any other non-gaming, heavy use application (rendering, video/photo editing, encoding, etc.).
Since you're looking more at gaming at it's main use, I'd seriously consider dropping in at least an HD 5770 ($100-125) or a GTX 460 1 GB ($175ish). Those will drastically improve your performance. However, you'd soon be constrained by having a dual core CPU, as more and more games are begining to make use of quad core CPUs. You could spend another $70ish for an Athlon II X3, or up to $145 for the X4 955, but you should be alright for now as long as you limit background activities while gaming.
A 3.3GHz dual core CPU isn't that bad, but depending on your resolution, visual options and games, the 9600GT could definitely be your biggest bottleneck. I think the x2 560 is a unlocked "black edition" isn't it? If so try to OC to get more out of it and it shouldn't hold you back to much for gaming.
I agree with MadAdmiral if you were going to build that at least get a better board so that you can upgrade later on if you want to. You are going to be severely limited with only one pcie 2.0 slot and only 2 slots for ram. Would reccomend JetWay JHZ03-GT-LF AM3 AMD 880G HDMI Micro ATX AMD Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E168... for only $15 more than the ASUS.
well i am visiting family and have the motherboard memory and cpu i did do a makeshift build with using a spare PS they have. I unlocked the other 2 cores and with very little overclocking got it to 3.5 and runs like a champ. I only have stock cooling so dont want to push too hard right now. Also there seems to be a problem sometimes when you unlock that no software can see the temps ive tried them all. Looking at it my video card is my weak point. I used prime95 using 100 cpu and memory and i could still navigate windows really well.
So this is going to be my build, and i got it at a pretty good deal. the motherboard was free with $99 phenom IIx2 560 BE the memory was $49 per stick so i got 2 4 gig sticks so it was about 200. The case PS,harddrive and Video card are off an old system. So i think it worked well
