A couple of things to note. Where graphics card is concerned, you really could do with at least a GTX 650 for gaming, the 630 is a bit too weak. You need to check the motherboard manufacturer's CPU compatibility list to make sure your processor will work with it, because the CPU is socket AM3 and the motherboard has socket AM3+. There are minor differences but, it is likely to be OK. I would suggest you buy Crucial ram direct from Crucial, so you are covered by their compatibility guarantee.
