My current system:

AMD Phenom II X4 840 3.2GHZ
Wester digital 1.5TB 5900K RPM
Asus Motherboard
Thermaltake 750W PSW

Option 1:

G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866
Mushkin Enhanced Chronos 2.5" 120GB SATA III
XFX HD-687X-CNFC Radeon HD 6870 2GB

Option 2:

XFX HD-687X-CNFC Radeon HD 6870 2GB
G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866
AMD Phenom II X4 975 Black Edition 3.6GHZ

Option 3:

G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 <-------
Mushkin Enhanced Chronos 2.5" 120GB SATA III


I do plan on upgrading to the Intel 2011 plarform in the next 6-8 months, so I'm looking for the option that gives me the most performance untill then.
