HD6870 a reasonable upgrade over HD5670 1GB?

Yes, it is a significant update.

I'm not sure what games you play, but you may wish to consider an even better card than that.

I know it will likely be $300 but the GTX660Ti is supposed to be out in the next two months and it's going to be an amazing value.

It also depends on the games you play.

I had an HD5870 which is very similar to an HD6870 and it played Skyrim (without the HD texture pack) at 1920x1080, high quality 60FPS.

I recommend:
1) seriously consider spending $300 on a GTX660Ti or similar HD7xxx card
2) compare benchmarks
3) get a non-reference cooler (whatever card you get) for lower noise
4) quality brand and read customer reviews on THE EXACT CARD YOU BUY

This is way BEYOND YOUR BUDGET likely but I think it's worth reading as there's a lot of good info:

Games wise, I'm not doing anything too crazy.

Borderlands (and sequel next month), SC2, Diablo 3, Texture Modded FO3 and FONV.

I'm mainly looking to be able to play most current games w/ good results, and really stay up with a couple upcoming games...maybe keep myself playing new games for a couple years.
