I'm building a new computer as mine has crapped out, however the current gpu is working fine, I'm trying to decide whether or not I need to replace the card now or wait until I have more cash handy to go for something more extreme.

My current card is a Radeon 6870 (1GB XFX HD 6870, 4200MHz GDDR5, GPU 900MHz)

the chosen parts of my new build are:

Intel i7 3770K, Ivy Bridge, Quad Core, 3.5GHz, 5 GT/s DMI, 650MHz GPU, 8MB Smart Cache
H80 Hydro Series cooler
Asus P8Z77-V PRO, Gen3, Intel Z77 Chipset
8GB Corsair Dominator Platinum, DDR3, 2133MHz

Already have:
Coolermaster stacker case
Tagan 700w PSU
Radeon 6870
Creative audigy fatality
700gb Hard disk

Usually its the other way around, CPU bottlenecking the GPU. In your case no it won't. I would suggest that you go for an i5 and use the extra cash for a GPU fund since there's not much difference in the i5 and i7.

hmm, If I went with the I7, I could get one of these:

2GB EVGA GTX 670, 28nm, PCIe 3.0 (x16), 6008MHz GDDR5, GPU 915MHz

But if I dropped to an I5 processor (i5 3570K,1155, Ivy Bridge, Quad Core, 3.4GHz, 5 GT/s DMI, 650MHz GPU) I could get one of these:

2GB EVGA GTX 680 Superclocked+ 28nm, PCIe 3.0, 6208MHz GDDR5, GPU 1058MHz

Interesting fact, according to Tom's Hardware charts the Radeon HD 7970 GHZ edition is faster than the GTX680 and on Newegg is $10 cheaper.

I can get a 7970 for approx 70 cheaper than a 680, I am however shying back into nvidia from ATI as some games are optimised for Nvidia cards, and a perfect example of this is Batman Arkham asylum, where it has "nvidia physix". I have seen this game with a gtx295 and with my current card, several graphical features are missing, including cob webs and smashing floor and wall tiles.

.
You might also check out performance comparisons via:
http://www.videocardbenchmark.net/gpu_list.php
Then click on the 'Rank' column to sort them in rank order. Keep in mind that published performance metrics usually vary greatly depending on the system, memory, programs used, etc. Even the same website can produce significantly different performance results by changing a single variable in a given test and bias in the conclusions is sometimes introduced by the observer for any number of reasons. It should also be kept in mind that a published number may change up or down as sample sizes increase.

Personally, I would be astonished if any website's published "performance" numbers are meaningful to within even +/- 5%, and TWO significant digits at best as far as the real-world is concerned.

Details on Passmark sample sizes, etc. can be found at the individual pages for each of the 'top 3' cards

http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GTX+680&id=41
http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GTX+670&id=35
http://www.videocardbenchmark.net/gpu.php?gpu=Radeon+HD+7970&id=51

Apparently the GTX670 is even less than the GTX680 or HD7970, but at those prices I wouldn't worry about $20-$30 differences.

You can always Crossfire another HD 6850.

I am however shying back into nvidia from ATI as some games are optimised for Nvidia cards, and a perfect example of this is Batman Arkham asylum, where it has "nvidia physix".

My opinion, you should never base your buying decision on what you've written above. NVIDIA's PhysX is flawed and not an open standard.

Optimized yes but it doesn't mean the other card is incapable of physx, as far as I know AMD cards can do Physx but will take a bigger performance hit when compared to Nvidia. I saw a chart reading on Tom's Hardware forums that it showed both cards doing in physx in Borderlands 2 and Batman and you need not to worry if using an Ati card since it will already provide more than enough frames for a smooth playing experience even if the loss is greater.

For example, Borderlands 2 needs just an ini tweak to enable physx on an Ati card:
