Would I waste a HD 6850 on a PCI Express 1.1 slot?

LOL ::- D. I see you have virtually the same configuration to what I'm aiming for. I got an E 6600 (ancient) CPU and would like to push it to E 7500 or maybe even E 8400 like yours.

I see you already got the 6850 ::- D.

One more question, since you're here ::- D. I was also thinking of going "cheap bastard" and plug in a HD 6670. After all, it would still be a massive improvement over my ancient nVidia 7950 GT. Does the PCI Express slot on this mobo feed enough power? I keep hearing that 6670 works without additional power connectors. But people probably mean PCI 2 slots, not PCI 1.

I'm getting a new computer and leaving this one to my girlfriend. A 6670 would probably suffice for her gaming needs.

If the card doesn't need additional power then yes, the PCI slot will be able to provide enough.

No, it won't be a waste. 1st generation 16x pci-e is equivalent to 2nd gen 8x pci-e, which is plenty of bandwidth.

A single 6850 should be no problem on that board at 16X speed just don't even consider Crossfire even though the motherboard supports it.

If you tried to add a second 6850 it would run at 4X speed which would cripple the second GPU.

You can stick with a single 6850 @ PCI-E 16X speeds and be just fine.

I am not very sure, but my ASUS P5B Deluxe motherboard has a PCI Express 1.1 slot, 16x.

Would I waste performance if I plugged a Radeon HD 6850 in it? I do not intend to game at more than 1920 x 1200 resolution, single monitor.


I have nearly the same setup as you, I have a E8500 cpu though and a HD6950 card. Its been working for a month now with zero problems so you wont have any issues with it, and the 1.1 PCIE x16 slot wont slow your card down vs the newer PCIE spec.

Slightly offtopic here, but the only real downside to this "old" motherboard / cpu setup imo, is it lacks 2 pcie 16x slots for Crossfire...If it had that then it could hold its own still against newer stuff easily. CPU and GPU speeds havn't ramped up like they used to before the C2D came out.

Thank you everybody for your answers ::- D!

nenforcer: I definitely won't go CrossFire! I never liked multi GPU solutions and never will, I find them wasteful and too driver dependent ::- D. I prefer being patient, waiting 1-2 years until I get a single GPU at a great price. After all, there are pleeeeeenty of games to play ::- D.

peonyu: it's true that evolution slowed down a bit. I never had a computer for 5 years and see it still hold its own against the newer ones. Of course, it's a piece of junk with my E6600 (will upgrade it), but not as junk as my previous computer which turned to junk in just 3 years hehe.

AoS810: 6850, 6870, pretty much the same. I think I'm gonna overclock the 6850. I'm on a budget with this thing. Most of the money goes into the new computer, this is just a refresh of my older one, so I can pass it to my girlfriend.

Ben90: he meant that I can use PCI express 1 to power a 6670 without extra cables. I was curious of power output of PCI express 1 = power output of PCI express 2.

BFG10K: what about a 6670 which doesn't have extra connectors BUT it is intended for PCI 2, not PCI 1. Can PCI 1 power it? (Barfo's answer still left me a bit unsure).
