There seems to be some knowledgeable people posting in here, what are you opinions on me scooping up a used 6950 ? in the 200-225 range, just make sure its a 2GB model?
The more I think about paying $350, it's crazy... my cpu + mobo cost way less
What games do you intend to play?
What's your gaming resolution?
What's your PSU?
I think you should wait a week to see if GTX680 forces any price drops on HD7000 line-up. It might not, but it doesn't hurt to wait.
If you are buying new, HD7850 is a better card at $250 than a used HD6950 imo. The reason we think it's overpriced is because at stock speeds it basically offers the same performance as a card that's more than 1 year old. If you are buying new though, HD7850 isn't a terrible deal from what's available, but it doesn't quite move the performance/$ from HD6950.
I personally think $350 for HD7870 is too much. GTX680 launches this week for $500, which may mean $50 price cut across the entire HD7000 line. Maybe.
If you are playing WOW, Diablo 3, Starcraft 2, then HD6870 for $160 is a great card (even HD6850 will suffice). If you are playing Battlefield 3, Witcher 2, Crysis 2, Shogun 2, then a used HD6950 is prob. the minimum I'd look at. The problem is at stock speeds HD6950 isn't that much faster than the HD6870.
Just look at these charts:

HD6870 is the best bang for the buck right now if you are willing to tone down some settings and don't mind upgrading in 2 years. It's just 16% slower at 1080P than a $260 HD7850. Not bad, especially if you don't care to mess with overclocking, etc.
Here is a personal tip:
I tend to buy $175-250 GPUs and upgrade every 2 years rather than choosing to buy a $350-550 GPU and keeping it for 4-5 years. I have found this strategy gets me more value over time (especially since cards get much faster 2-3 years out while a brand new $550 card is too slow in 3-4 years). In that regard, it's better to get a $160 HD6870 today (put aside $190), keep it for 2 years, and then get a new $200 card in 2014 rather than to buy an HD7870 for $350 today and keep it until 2016. If you can find a used HD6950 2GB for $180-190, also good deal to start your path. Alternatively, there are used HD6870s too.
However, this can't work if you need to max out every game all the time, play at 1600P, game on multiple monitors, want the best features that new cards have, want the benefits of lower power consumption of newer cards, need to have the latest and greatest, etc. This is my personal budget approach that I find has worked well. Some other people on our forum get $500+ cards and try to sell them before they plummet in price significantly right before the next generation $500 card is out. This requires very tricky market timing and constant reselling. This can also work if you do it right but if you miss the timing your card may plummet hundreds of dollars in a matter of months if not weeks.
Just to give you an idea a $500 GTX480 came out March 26, 2010 and Newegg had a sale on it for $210 just this month, and last year it was on sale for $175-200 on Newegg as well.
