In terms of overall CPU processing power, Intel wins. There is simply no contest. Even OC'ed the A10 will still lag behind Intel's i5-3570k at stock speed. Or at best match it (unlikely I think). The A10 does have it's usefulness though.
The A10 would be great for a low budget gaming rig especially since it is on sale. As long as the graphics card is a Radeon 7670 or slower, then you can gain a small boost in performance with hybrid Crossfire. I'm guessing the performance would be close to a Radeon HD 7750, but that's just a guess. But as you stated, that does not matter for you.
