Hello!

I plan to upgrade my current vga nvidia gtx 470 to a gtx660. The problem has many sources.. as always:
1. I have a Asus p6t Deluxe v2 Motherboard which only supports pci 2.0 the card is 3.0 unfortunately. Does it have certain disadvantages, i would be glad for some exapmles.
2. i have core i7 950 3.1 Ghz cpu , and somewhere i read the pci 3.0 vgas works well with only the 3th generation new cpus 3xxx . Also what are the disadvantages, in some values (maybe FPS , i'm a gamer)

Well I have a power supplement 750W so it rarely cause problems.
I'm w8ing for the experts answers, whom are sure in their things.

dont worry PCIe 3.0 is backwards compatible with pcie 2.0 and it wont bottleneck much and your CPU wont bottleneck the card. its a very capable CPU.

Best solution

Regarding the scaling of PCIE with the Kepler cards, this article shows a GT 680 on different PCIE connections. Because the 660 is also Kepler, it's safe to assume the results will be the same.

As a gamer I would look at these two pages specifically:

FPS/Fast moving GPU intensive game

RTS (Low GPU usage)

To answer your second question, it's not that PCIE 3.0 are better with the 3rd generation core i CPU. PCIE 3.0 is only supported on an LGA 1155 motherboard (which support both the third and second gen core i) but the architectural change in the Z77 (third gen motherboards) was designed for the PCIE 3.0 so it wont come as a surprise that it works better with it.


So just to clear things up, going from PCIE 3.0 -> PCIE 2.0 wont cause that much of a performance issue, and although your CPU isn't 2nd or 3rd gen, it will still be able to handle things without breaking a sweat.

There will be no compatibility issues and your CPU is more than fast enough not to bottleneck the card.

The tests above show that the 680 performs about .01% better on a 3.0 x16 slot vs. a 2.0 x16 slot.

So the performance difference is negligible at best. Not to mention the 680 they've tested with is going to be filling a lot more of that bandwidth than your 660.

So basically it would be lot better even with these config?
What would be the differences between with this (i7 950, asus p6t Deluxe v2) and a full pci 3.0 supporter mobo, and a third gen cpu in a scale of 100?

well on a scale of 100, that 3rd gen CPU's performance will be 100 then your rig will be 99.7. the differance wont be noticeable. so your better of with a GTX 660 in your rig.

Agreed.

Can you save more money?

It will not be a big upgrade to be honest.

it will be a lot easier on the power though.

One word of warning, and not saying it will happen to you. I had a PCIe 2.0 Gigabyte P55-UD4P board. Everything is great. I put in my Gigabyte WF3 7950, not so hot. Randomly, and I do mean randomly, I would lose my monitors. They'd just go black. At least once a day. Maybe the mDP to DVI adapters, maybe my eyefinity setup, maybe my bios needed to be updated. I don't know. I do know the problem went away when I put in my Z77-UD4H. I'm back to rock stable. 3.0 should work just fine with 2.0 boards. I personally had an issue. Which a bios update would have probably fixed. Just throwing my experience out there.

IDK...
GK110 is suppose to much better than GK104(Curent Gen)

And either way, waiting will allow prices to drop. Worst case he just gets a Curent Gen at the same price. A lot to gain with nothing to lose.

7870Xt would be the next real step in price and power or as mentioned maybe wait for the new 7xx series nvudia card.
