Unless you really can't persevere with the micro-stuttering and heat, it would be better to wait until the end of the year and get something that both resolves the above problems and yields an improvement in performance.
i would wait, 100% wait! few months could see a whole new set of cards comes out
Either a 7950/7970 or 670/680 with an overclock should match/beat the 6990 in most games. So it's down to how much you really want to spend and which brand you'll go with.
+ 1 for HD 7950 @ 1080p
+ 1 for HD 7950 @ 1080p
Gtx 660 ti is a good card in the same price range
Overclocked, the HD 7950 is just the best bang for buck card IMO. The OP wants a card now, new releases are too far away for him and his IGP is not going to do the job. Therefore, and once again, IMO, the HD 7950 is the go to card.
The only other option would be GTX 670 and that reccomendation is ONLY if Physx is required or important to OP, otherwise HD 7950 and overclock it to unleash its potential.
Not particularly looking for a performance increase as the 6990 ran every game Ive got faultlessly, but conversely I dont want to lose performance.
Bit too late, the 6990 is on its way to its new owner this morning so I'm running integrated graphics at the minute off my 2500k
He doesn't want to lose performance and a 7950 doesn't give more performance than a 6990.

7970 is the only thing, outside a Titan, that will match a 6990

But there's only a 5% difference between a 7950 and 7970...?
The Anand bench facility is:
a) stock clocks on both
b) woefully out of date on the driver front
If OP is willing to move a few sliders and overclock it the 7970 doesn't offer any meaningful increase in performance over the 7950 other than benchmarks.
And it's most definitely NOT the extra VRAM which helps the 7970 GE vs 6990.
Wow, set a bit of a little debate off here
Finally decided on the 7950 which combined with a decent overclock should hopefully do the job nicely.

Thanks for all the suggestions/advice etc.
