Hey guys,

I'm looking to upgrade from my 8800gts 512mb and I have my eye on the new GeForce GTX 470 (Fermi) on Newegg. My concern is that I am running a P35 northbridge which only supports PCI Express x16 v1.1 instead of 2.0. I have read a lot that current cards have yet to max out the 1.1's bandwidth and thus isn't a bottleneck, but has the new generation reached that point? I realize that he card will still work with 1.1, but,

Will a 5850 be bottlenecked by PCIe 1.1?

Thanks

As far as I am aware it wont be bottlenecked by 1.1. Your CPU (depending on what kind you have) could end up being more of a bottle neck

Unless you play at resolutions of 2560x1600, it will not be bottlenecked.(But it can be bottlenecked by a slow CPU)

A 470 and a 5850 I think would both bottleneck under the 1.1 standard (also depends on your other components too, CPU, RAM, etc).

Edit: Emphasis on other components. PURELY on the 1.1 bandwidth standard, then no, but you can end up bottlenecked.

Here's my comp specs from Sanda sisoft
p35-ds3l MPS 1.40
Corsair 4gb ddr2
Core 2 Quad Q6600 2.4 running at 3Ghz

My original thought was to upgrade motherboard, RAM, and Video... Although if this machine will be able to handle new generation Video Card, it should be alright for the next couple years (for crysis 2 :) ) .. what are your suggestions? is that about time to upgrade my motherboard and RAM as well?

thank you!

I don't think the P35 does support DDR3 (mine certainly doesn't), do you have two different kinds of DIMM slots?

You are correct mousem, it does not.. will have to run ddr2 for couple more years..

Just got GIGABYTE GV-N470D5-13I-B GeForce GTX 470 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 for $252 (after $25 promo code and $20 mail in rebate).. Which was pretty cheap, could not pass this deal.
