I currently have sli'd GTX 460's and I think they do pretty good but tonight I saw GTX 470's for sale at $100 a piece with free shipping on ebay. I couldn't resist buying them because I figured I could probably get most of my money back out of my 460's. The specs on those 470's look way better than the 460's. I'm always looking to get the most performance possible for $200 or so and I think I've found the best deal possible for that price range. At first I was thinking that the performance boost might not be worth the hassle of trying to sell my 460's but I wanted them. The extra 256MB of vRAM might come in handy for future games as well as the extra core count. I guess if I can even come close to breaking even then it will be well worth it.
