Does my Core 2 Duo Bottleneck a 750 Ti?

I plan to buy a GTX 750 Ti and I'm unsure if my current system can bottleneck it or make the graphics card not work at all, since the motherboard supports PCI-E 1.1 max and the CPU or RAM can be too weak. Here are the specs:

Intel Core 2 Duo E7500 (~3Ghz dual-core CPU, 3MB L2 Cache)
4GB of DDR2 800Mhz RAM (Dual Channel)
MSI G31M3-L V2 Motherboard (G31 Chipset)
600W Power Supply (I know, its a little overkill.)

Yes, there will be some restriction, how much very much depends on the games you'll be playing, but you should get playable frame rates provided you keep the CPU limitations in mind and dial down CPU heavy effects like smoke, explosions and object details.
Davidarad02 is incorrect, the card should run in a PCI-E 1.1 slot, PCI-E is very backwards compatible and Nvidia seem to have fewer problems running even their latest cards in older motherboards.
And no, the GTX750Ti isn't fast enough to suffer any further bottlenecking with a PCI-E 1.1 slot (it will, but just by a few percent, you'll need to run benchmarks to see the difference.)

Fast Reply, by the way. Thanks.

I did not know that this would not work in anything under pcie gen2, and I was not expecting that my CPU would bottleneck this card, because it is one step down from a Pentium G3258, which would run this card just fine...

Well, I guess its time for an upgrade.

I have an E8400 system with a 7850 HD GPU, 8 GB RAM. I tried to OC the GPU, after I OC'd the CPU by 20% and memory by 27% - Only to reveal, that only a small OC changes anything, and that's it.
So I guess I'm GPU bottlenecked, and it seems probable that the 750 Ti will be too, on your system, if somewhat a little less BNecked. (http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html)

There was lately an article in PCGamer about this issue.

his case is not the same as yours, because AMD cards (even 7000 series ones) are not limited to gen 2 16x, because AMD does not lock that down. nvidia does.

Oh wow, what a relief, because I don't have the money right now for a new PC and my current graphics card died, so im stuck with the really, like REALLY bad integrated graphics of this CPU (GMA 3100) and the 750 Ti interests me because its cheap, it performs quite well and it has CUDA, which can accelerate video rendering, since I am starting a YouTube channel. Thanks for explaining this for me.

i do not recommend starting a youtube channel using this stuff, this is really slow, and rendering times are HUGE.

^+1, the old dual core CPUs aren't totally dead for gaming-if you keep their limitations in mind-but it's not really fast enough for video work, if you want to do that you'll need to look at upgrading to a much faster CPU and bringing the memory up to at least 8Gb-which will mean installing a 64 bit version of Windows if you're currently using a 32 bit one.

I do use a 64 bit edition of Windows, and I aleardy did a few videos, and I did not have any problem and it wasent waaay too slow (8 mins for a 2:10 720p video)

I will upgrade my CPU to a Core 2 Quad Q9550, how about that? Since it is preety much an equivalent to a Core i5 when it comes to cores, so I think that might do the trick. What do you guys think?
