Well i guess other folks had issues with it, but i sure don'.t Works perfectly on my Pentium d. I understand the green edtion may be less powerful in terms of specs or whatever, but for 65 bucks you can't go wrong you know. Best buy has these cards for 65 dollars in the clearance section all the time. Its really a powerful card, allows me to play games really good.
On another note, i was planning to stick with non power connector cards, but i am in the process of upgrading my pentium d and might end up buying a 5770 which only requires one 6 pin which i have on my psu.
