I've recently come upon a deal on a 6950 2GB. A friend of mine is selling his for $100. I currently have a 6870 1GB, and I mostly game at 1080p, though I'm looking at one of the Korean monitors within the next year. If I got the 6950, I'd probably use my current 6870 to mine Litecoins with. Is it worth it to upgrade my current system (specs in signature) with it given my usage?
