GTX 460 vs HD5770

The 460GTX (especially the 1gb version) performs better then the HD5770.

Neither, the 460GTX doesn't even have the pricepoint to compete with the 5770, although it is better than the 5770. At the price of a GTX 460, you might as well go with the 5830   Much better deal. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The performance of the 460 is good though for the value, the 1gb vers. is more expensive than the 5830 1gb vers. But thats a little thing. The most I would be assessing is the overclockablity. Since the 5830 is indeed cooler and less pwr consumption vs the 460 gtx 1gb I would expect the 5830 would be able to overclock better. Seeing the 5830 i posted already as stock is minor overclocked. And personally, http://www.overclockersonline.net/news/his-hd-5830-icoo... That shows the overclockablity of the card i showed.   But it's your choice, i personally love ATI so, the 5830  

They're both good cards... The ATI has the advantage of having 3 video outputs so later on you can create an Eyefinity 3monitor setup, whereas you'd have to get 2x GTX 460 for the vision surround with the Nvidia card. On the other hand, if you think you might wanna try out 3D stereo gaming then Nvidia is the only viable route.

These cards perform similarly but the 460 is usually quite a bit ahead of the 5770 and a touch shy of the 5830 (~1fps). check out the review of the 460: http://www.tomshardware.com/reviews/geforce-gtx-460-gf1...

If I were you, I'd go with Nvidia. They usually have better and more stable drivers, and with the revised GF104 fermi architecture, they solved the problem of immense power draw and hence heat that are associated with the GF100 series cards (465, 470, 480). Also, this gives the 460 a huge Overclocking overhead as shown in Tom's review of the card.

The link you referenced showed the GTX460 768 to average 6% better than the 5830. The 1gb version was 17% better. Since the price point was the same, I would not conclude that the 5830 was better. Apparently, the GTX 460 is a very good overclocker also. I think the 5830 will need to drop in price a bit to compete.

To maximize longevity, the OP should get the stronger GTX460 card. Bang for the buck is not bad either.
