Upgrading video card?

I have a PCIexpress 2.0 x 16 slot and can I put a PCIexpress 1.0 x 16 graphic card in it?



(Optional Question) Also which graphic card is better:



ATI Radeon X1950PRO 512 MB



or the



GeForce GT 430 1024MB



I like the Radeon because it has a higher score on http://www.videocardbenchmark.net/gpu_li…|||PCI is backwards compatible so yes you can,



personally i would prefer the GeForce, mainly because i dont like ATI as well AMD, and i'd prefer 1024 MB on ram above 512 MB of ram, but if it has higher benchmarks then who am i to say you shouldnt.|||Your question is a bit confusing... your motherboard has a PCI 2.0 x16 and your card is a PCI 1.0 x16 or your motherboard has a PCI 2.0 x16 and you want to put the card into a PCI 1.0 x16?



Any way just you should know you always put the graphic cards into a PCIx16, also the PCI 1.0 I think is a bit outdated,newer card have either 2.0 or 2.1 (which is more or less the same), and yes you could.



Optional Question:



In this case (although I like ATI) I'll go with the GeForce GT 430 1GB since it has more RAM than the ATI|||I have used both brands and found that you get better with nVIDIA who make GeForce. The Radeon you are looking at is a discontinued model. Both have built in fans on them and the GeForce fan is much larger and easier to clean than the ones Radeon uses. Which ever one you use you need to clean once a month with air in a can and do so carefully. I threw away a Radeon that cost $300 because the fan became so clogged with dust that it caused the computer to freeze and I could not get all the dust out of it do to it having such a small fan.



That being said I have an iMac 27" with a ATI Radeon HD 4850 as it was more powerful than the nVIDIA that was available and I have yet to have any problems with the Radeon card this time around.|||Well, depending on your power supply, and case (saying that you already have this information understood)...You CAN put a 1.0 x16 in a 2.0 x16 slot, but you won't get any boost in performance...as far as what I think you're trying to do, which is getting a liiiiittlle more bump out of your system, go with the Radeon...unless you have an intel processor, then go with the GeForce...|||Your Passmark chart is not reliable. It is only of vague accuracy since the scores are all user submitted and doesn't take factors from many different systems into consideration sych as:



Which CPU it is paired with

How much RAM it is paired with

Does it have new or old drivers?

Is the card overclocked?

Is it bottlenecked by another component?



I'd go with the 430 or even better with a 450/460|||What? Has a pciexpress 2.0 x 16 slot?? Who has a pciexpress 2.0 x 16 slot in the first place??
