GPU Upgrade, Looking for CUDA 5.0

I currently have a PC without a discrete GPU. This is a work-based PC (Dell Optiplex 7010 to be precise) with a Core i7-3770 CPU, 8GB memory and a SSD. I recently got a "warning" from Adobe After Effects letting me know that ray tracing on the GPU only works with a CUDA 5.0 enabled discrete GPU.

So, in looking on nVidia's website, I'm noticing that desktop GPUs as the 8000 series are CUDA capable with varying "Compute Capability" levels.

So now the question(s): What level of GPU would I need in order to notice a quantifiable performance boost? What type of performance difference should I expect between difference levels (no discrete GPU vs. 8800 GTS vs. 210 vs. 640 vs. 750 Ti)? Can you recommend any benchmarks/charts that could help me make my decision?

I recommend the Asus GTX750Ti (about $155 USD).

I don't have any good benchmarks, though once you go above this point the OVERALL rendering time difference between this card and a TITAN tends to become very small.

The GTX750Ti uses the new MAXWELL architecture for its GPU which is more efficient for CUDA. I picked the ASUS card in particular because it's got a relatively quiet cooler.

"...but pay attention to the size of the GTX 750 Ti’s increase. Double the cryptographic bandwidth. 42% improved encryption/decryption performance, despite fewer CUDA cores and a smaller memory bus. 4x the hashing bandwidth for SHA-256 operations..."

Anandtech usually does a good job of covering compute in its GPU reviews.

Thanks for the response photonboy. I was starting to lean towards the 750 TI myself because it looks like it may be the best budget bang for buck (and doesn't need extra power) when remembered it will also have to be a low profile card.

The best I'm finding through Newegg (which I can then locate on Amazon as well) is an MSI N640-1GD5/LP.

There has allegedly been a low profile 750 Ti released by Galaxy, but I'm not finding it in any US stores. That seems like it would be the ideal right now.
