4870 > overclocked 8800 Ultra 100% of the time?
Hey guys. I currently have an overclocked 8800 Ultra that has been very good to me the past year. I was very anxious to get the GTX 280 but the price is scaring me away as I have a lot of other financial obligations over the next couple months. I was going to get the GTX 260 instead but noticed the 4870 does really well against the GTX 260 at over $100 difference out here in Canada. The idea of saving money has really got me thinking. I do want to upgrade my card, but I do not want to spend money unless it is a drastic jump. I do know the GTX 280 will be a drastic jump but a $700 jump I am not so sure. I am wondering if the 4870 is 100% faster across the board than my current card. I have read tons of reviews but most don't pit the 4870 against the 8800 GTX/Ultra, especially not overclocked models as a comparison. I am worried that the 4870 won't quite be that much faster over my 8800 Ultra or will it? The benches for certain games seem very low compared to the Nvidia cards such as Lost Planet etc. I don't want this to be a trend with the 4870 when comparing it to my current card.
Would one say the 4870 is a worthy upgrade over an overclocked 8800 Ultra or should I just spend the extra coin on the GTX 280? I am assuming the GTX 260 is a no no if the 4870 is since the 4870 is neck to neck to the GTX 260.
