Hold on, I thought the point of the GTX was that it was newer so it had near equivalent power to the 8800GT but took up one slot.(Edit Oops, I was actually thinking of the 9800GT) The GTX+ has more power than the GT but I didn't think it took up another slot for it.
I'd call this an Edit but seeing how I haven't even posted yet It isn't.
It turns out it is dual slot, but if you want something of near equivalent power that is single slot I'd have to direct you to (definately not reccomend, oh no, no way, no-ho-ho, no) the HD4850 or the HD4830.
The HD4850 is slightly (only slightly) worse than the 9800GTX+, but it does have better anti-aliasing. The problem is though it is generally noisy, it has terrible power management, and the single slot cooler means they get
hot.
The HD4830 isn't quite as good as the HD4850 in terms of power, but does run cooler, is a bit less noisy, and is somewhat better with the enregy issues, but is essentially the same chip in hardware terms.
However if you are looking at the HD4830 I could direct you to the nVidia 9800GT, which is pretty much exactly the same as the HD4830, even in price, and generally performs slightly better than the HD4830, but does fall slightly behind when Anti-Aliasing is acivated.
And sorry I can't give you a personal recommendation, I have an nVidia GTX260 which being dual-slot I think is out of the question.

As for ATI, I have no idea. I'm an NVidia guy.
Also, I heartily agree with BloodEagle, I always try to buy nVidia instead anyway, because their drivers are generally better, and nVidia chips are generally used in conjunction with the developers of most games e.g Crysis and Unreal Tournament 3 are both optimised for nVidia cards. Many of the ones that a PC will struggle with usually are nVidia supported, such as the aforementioned Crysis.
