I am using a 560 GPU in an older HP workstation xw8600. I use this for video editing solely. I edit with Adobe Premiere Pro 5.5, which has CUDA acceleration. I am considering stepping up in CUDA cores to a 600 series card, namely the 660ti. This card is listed as PCIe 3.0. My question is will I incur a bottleneck using a PCIe 2.0 slot for this card-or should I stick with the upper end of the 500 series cards (580,590 etc.)? I think all 500 series cards are PCIe 2.0 (please correct me if wrong). I experienced a big jump moving from the the 550ti to the 560. There is a boost in Adobe and it looks like the more CUDA cores the better the scrubbing a playback from the timeline. I am only editing and doing some light color correction, no gaming and am looking only to optimize for this specific use. I am a little committed to the xw8600 at this time, so a mobo swap is out. Thanks for any and all comments.
So you need CUDA? Well if so, yes that slot will work fine. As I assume it is x16? It would probably work fine with x8.
Thanks for the response. Yes that slot is x16 PCIe 2.0. My question has more to do with the 2.0 vs. 3.0 bus recommendations for the cards. Will a 3.0 spec card (like the 660ti) be hampered or bottlenecked by being seated in a 2.0 slot (yes, an x16 slot)?
Or should I stick with the 500 series cards which seem to be designed for PCIe 2.0? Thanks
