I want to change my old 65nm XFX GTS250 1GB to HD6870, but i know that most of the hd6870(maybe all) are 2x6pin, so i want to ask is there hd6870 with 1 6pin reqiured? If no , then i think i will change my GTS250 to MSI HD6850 Cyclone with 1x6pin, do you agree that it is the best option ?
This is my system:
Q9400 2.6GHz OC to 3.6
4GB DDR2 800
Also i dont want to buy a new PSU!!
The HD6850 is only 2 tiers higher than the GTS250. To see a major performance improvement you will need a 3 tiers difference. The HD7850 is soon to be released. It may have 1x6pin and at least a HD6870 performance.
