I have an almost complete system left over from recent upgrades. The main thing I am down is an OS. I bought a retail copy of 7 when they were on special.
Now I am thinking of flogging the old kit to a friend for as little as possible. I'd probably take the opportunity to upgrade my GTS 250 to a GTX 460/HD 6850 if that helps with OEM purchasing.
What is my best option?
