With respect, the only benefit to the AMD A10, is good on board graphics. If you have a seperate graphics card, that benefit is wasted. As a processor, the A10 is beaten hands down, by Ivybridge Intel, even i3.
Do you have any particular games, you want to play well. It's probably possible to put something, better, for your budget.
Well I'm trying to play games like Guild Wars 2 on max, then I might get more games like Battlefield 3. I'm trying to get more into PC gaming. I've been a PS player for a long time.
