none of them

What are you going to do. Gaming and 3d programs, rendering or just MS Word?

Id get the #2 if I was gaming and stuff but maybe #3 for processing

 

[larrym]

Best for what purpose? They all look pretty nice for gaming..some over kill here and there. 2 and 3 would be better for video editing. How many monitors? what resolution?

 

[getochkn]

Best for what? Are you buying these systems premade? They seem to be all over the map in terms of components. I5+680, good for gaming but 680 is overprices. I7+670, I7 is overkill for gaming.then an AMD 8 core with crossfire 7870's?

 

[Chrisis]

Yes they are premade and yes mainly for gaming

What are the prices on them? It would help to determine if say system 2 and 3 are only $50 apart vs $250 apart.

All costs exactly the same except #3 which is on sale normally a bit more pricey

 

[Chrisis]

I think i will pick #3 in terms of Stability and low low CPU heat

+1

Out of those, I would choose the 1st build solely for gaming, and the 3rd build if you were to do video-editing. The 2nd build would suffer from microstutter with two 7870s in X-Fire, while you'll probably see some better performance. It may have a slight CPU bottleneck though.
But, if possible, build your own PC. It's cheaper, and you can use the money you've saved to put into a better GPU/CPU etc. It's more satisfying and you'll get better results for (less) money.
