I just wanted to know whats everyone opinion on Diamond as a OEM? What is their support like? A little while ago I decided to upgrade my 5870 earlier since I couldn't wait for the next gen. Anyways I started looking at 7970s and was about to buy the best, but then I thought to myself why not buy a cheap one and sell it when next gen comes out and get the new one thereby lowering my overall costs since I was most likely to buy the next gen since I was going to do an overhaul anyways. So I found a Diamond HD 7970 non GHZ edition on craigslist for $250 and I just wanted to know if its ok to buy. Also what can I do with my 5870? I dont think there is any advantage in keeping in my system such as Physx or some weird crossfire.
