I am planning on building my own PC know the dilemma I have is with the ASUS M5A78L-M and the DDR3 problem. I would like to know a graphics card that would be good for games like G.T.A. for example.Also, I need a good power supply. My part list is :-
ASUS M5A78L-M/USB3 Motherboard
Cooler Master K281 Mid Tower Cabinet
Dell S2240L 21.5 inch LED Backlit LCD Monitor
AMD 4 GHz AM3+ FX-4300 FX-Series Four-Core Edition FD4300WMHKBOX Processor
Seagate Barracuda SV-35 1 TB Desktop Internal Hard Drive (ST1000VX000)
Corsair Vengeance DDR3 8 GB (1 x 8 GB) PC RAM (CMZ8GX3M1A1600C10)
Razer Deathadder 2013 6400 DPI USB Optical Gaming Mouse

Thanks a ton so now the thing is that I have chosen a ZOTAC NVIDIA GTX650 Synergy Edition 2 GB 128-bit DDR5 2 GB GDDR5 Graphics Card however my mother is a ASUS M5A78L-M/USB3 so will the graphics card work and will I need a higher wattage for the power supply?

Yes.

Psu will still be sufficient

I would recommend a GTX 750 or a 750 ti and it does not need to be plugged into a PSU

But the GTX 750 is a DDR5 but my motherboard is DDR3 with a PCIe 2.0 x16.

lol my gpu is ddr5 pcie 3.0 and i put it in a pcie 2.9 x16 slot, there is no performance difference. GPU's cant full up the bandwidth of a 2.0 slot yet.
