PCI Express 2.0 x16 question

Hey, I have a motherboard with a PCI Express 2.0 x16 slot. Is a PCI Express 2.1 x16 video card compatible with it?

Thanks

Yes it is completely compatible, if you put 2.1 on 1.0 then that's a problem. But you should be fine.

Hey thanks!

I actually have another question.

The video card I currently have is a BFG Tech BFGEGTS2501024E
http://www.newegg.com/Product/Prod [...] 6814143191

The video card I'm thinking of getting is the MSI R6850
http://www.newegg.com/Product/Prod [...] 6814127576

My current card has a Effective Memory Clock of 2000MHz while the one I'm thinking of getting has an Effective Memory Clock of 1100MHz (4.4Gbps). Does that mean the one I have is actually better?? Basically, I want to get a card that is slightly better than what I have now & also a lot quieter.

Thanks

hd6850 > 2xgts250.
its more than double in performanmce.

No, I think it's because your old one is GDDR3 and the one you want to buy is GDDR5. And yes the 6850 is better, I'm not sure if it will run quieter, but I think it would run quiter.

Good Luck

What you wrote doesn't make sense.

GDDR3 like on your GTS250 is "double pumped", meaning it can transfers 2 bits of info per clock cycle. So the "effective memory clock" of 2GHz means is actually running at 1GHz, which is normal for GDDR3.

GDDR5 on the other hand is "quad pumped", meaning it can transfer 4 bits of info per clock cycle. It's effective memory clock should be 4.4GHz, and actually running at 1.1GHz, which is normal for GDDR5. If where you're looking at has it written as EMC at 1100, it's probably a misprint.

The 6850 is faster then a GTS250. Its similar in performance to the GTX460. (which is like a GTX280/285.) It's a much faster card. Don't know about quieter as models are different depending on the cooler.

Hey thanks guys!

It's good that the performance is better but I'm also looking for something that is quiet. Any idea of a card between $125-200 that is quiet?
