You have a decent motherboard and CPU. You need storage space, and most likely a graphics card, possibly a new PSU depending on what you have.
Things you can have that would fit a potential later upgrade and improve your current setup :
- CPU cooler (£30-£50). Overclock to 4GHz.
- SATA3 SSD (£100-£150). Just use as SATA2 in the meanwhile.
- 2TB storage drive (green drive, £60). Frees your 1TB drive, which should be relatively fast. Drive speeds have little impact on gaming.
- latest gen graphics. 6950 / 6970 / 570 (£200-£240).
- 650W+ PSU (£70).
- 8GB ram (£60). Don't bother with expensive high profile ram, just some seasoned 1600MHz ram.
Those would be what I'd focus on. That also gives you time to assess BD, and then decide if you should go sandybridge or bulldozer. The rest can be transplanted easily into whatever CPU + MOBO config you fancy, once the BD water clears out. If you are running Win 7 OEM, then you will potentially need to factoring the cost of another OS key when you change the motherboard.
It's still better to upgrade everything at once, just for saving on shipping costs alone. And less messing about with the OS, drivers, and poking around the case. The advantage although is that you can find out if a component is faulty relatively quick, since it reduces the variables (install RAM, problems, then most likely the ram itself).
my £0.02's worth.
