Most powerful PCI-E 2.0 GPU?

I have already asked around to find the best value GPU and I was told about the GTX 760, which would be perfect. But it's a PCI-E 3 card and my mobo has 2.0. My current card is a GTS 450. If I can't get a much better card, I might just have to start over and build an all new computer.

PCI-E is mostly backwards compatible. A 3.0 card will work in a 2.0 or even 1.1 slot.

But what is your CPU?

it doesn't matter, a pci-e 3 card will work in 2.

I have a Phenom II x6 1045t CPU. I know they're backwards compatible, but wouldn't I lose some power from it?

There are a lot of people who are running PCI-E 3.0 video cards in PCI-E 2.0 motherboards. Anyway the most powerful PCI-E 2.0 GPU is GTX590 for Nvidia and HD6990 for AMD.

The performance loss would be a few percent at the most. Not a huge problem.

Would I get the same performance from the GTX 760 as someone with a PCI-E 3.0 motherboard?

Yes. It's almost no difference. Todays cards are just starting to fully use the 2.0 bus, nevermind the 3.0 bus yet. Your CPU might not be powerful enough for that card though. That's your bigger issue than 3.0 vs 2.0

Not necessarily. But you would only lose a few frames per seconds at worst.

Yes I'm aware I'll bottleneck the card slightly but I've been told that my GPU bottlenecks my CPU as it is.

Get a 760. It probably won't be bottlenecked by your card.

Your card is very close to the current 6300 and the 6300 does not bottleneck the 760.

Also do overclock to ensure that you remove the bottleneck as much as possible (if there is any)


Both my CPU and current GPU are oc'd 15%.

Just get a 760 if you can afford it. It should not be a problem.

If you cannot get it, then get the 7870 instead. It is also a good GPU. 660 is also as powerful and sells for a bit cheaper than the 7870.

Yeah I can afford it easy, I have a job with a friend as a Computer IT but I'm in training right now. So, I should be able to get this card next week. Thanks for the info. Where did that comparison graphic come from btw?

If you are talking about the CPU Comparision, then that is coming from CPUBoss.com . Pretty okay site to quick compare two CPU's. It comes in handy at times.
