My Venice tops out at 2385Mhz due to older mem controller. I currently have a 7800GTX single card. Will I see any real world gaming improvement in newer games like Oblivion at 1280X1024 resolution from this upgrade? I am only planning on doing moderate air cooling OC if I get the Opty 165. Not more than 2500Mhz. I found me a brand new Opteron 165 OEM for $275 and was thinking about buying it. How much do you think I will be able to sell the retail 3200 Venice for?
