Okay so I have decided to upgrade my video card from my current 8800gt, I would like to go back to ATI chipsets and I feel that the 4890 is the best bang for my buck. That being said I am just currently debating which is a better buy, the 4890 or the 4890xt. At the price right now we are really only talking about a $17 difference. Is the 4890 XT with the only notable difference being the extra 25mhz of core clock really that much of an upgrade?
I have chosen to go with XFX again as my last card the 8800gt was very reliable and I am quite happy with that brand. I also have a sufficent 600w power supply with the 2x 6pin connectors required to run this card. As long as I stay away from the XXX version which has a 8pin and 6pin I should be fine with this card.

Re: 4890 vs 4890xt
The extra clock speed is definitely not worth the extra money (there won't be any measurable difference between 25MHz). You can get more than that with a program like Rivatuner for free.
Take the first one, the price isn't justifiable for the performance difference and doesn't even have a better cooler and 25mhz is an easy OC
