I am going to upgrade my pc and get a totally new one and scrap the old one, pretty new to this and any ideas or anything just post on this. On a pretty tight budget so don't want to pay to much money but would like to play some good games maybe not all at ultra setting but decent enough.
Processor: AMD Phenom II X4 965
Graphics Card: GeForce GT 630
Motherboard: ASUS M5A78L-M/USB3
Case: Antec 600 V2
Power Supply: OCZ ZS750W
And some good Ram for it
1) GT 630 is a pretty weak card and the HD 7770 will do just fine with high settings based on your resolution. In fact with the money you saved you could step up to the HD 7850 if desired.
2) Power supply is an overkill, the VP-450 will do fine for the HD 7770.
3) 8gb is more than enough for gaming builds.
If this is for gaming you are definetly going to want something more powerful than a GT 630. That is a really low end video card and is not good for gaming. If you want a gaming card I would look at no less than a GTX 650 Ti or a Radeon 7770.
What do you think of the motherboard, that was the thing I was most hesitant to buy
It's okay, I'm running the phenom II X4 955 Black edition on the Asus M5A78L-M LX Plus and it works just fine. My motherboard is a bit different and older than yours I think. There are other alternatives but our motherboards are okay, we can overclock quite a bit with it.
I see no problem with the motherboard however you have to understand that it is a micro ATX and from what I can tell from looking at the pictures it only has one 16X slot. This means that you aren't going to be able to SLI or Crossfire with that motherboard down the road if you wanted to.
