It will help by quite a bit, although it will still bottleneck. I used to run an A4 5300 as well, and a GTX 650. I ended up upgrading to an A10 6800K and it helped a bunch. However, the poor single core performance and lack of L3 cache hurts it by too much to ignore. It will perform better, but not by as much as you would like. If you have the money, I'd recommend switching to an Intel Pentium G3258, and get a cheap H81 LGA1150 motherboard to go with it. Its only two cores, but its very fast and shouldn't have a problem powering that card. Hope this helps
