Clearance? You can't measure the clearance in your case?
You're asking us to guess when you should be able to measure and know for sure.
If there is any question in your mind the larger HIS card won't fit.... choose the XFX model.
There might be an issue with 2 SATA ports. You can probably retain use of one with a low profile, 90 degree SATA connector cable.
I think your RAM slots will be OK. You'll just need to remove the card to get access to the RAM.
The link to your diagram is broken.
Do you have the HP Pavilion a6110n Desktop PC.
Get a tape maasure and measure the distance from the expansion slot to the back of the HD or case component that would be closest to your card. Then look up the dimensions of the card you want to buy....if the 2nd number is smaller, you are OK.
Alright, thanks for your reply, i was asking around on another forum post, and the guy said that for an extra 10 bucks, i could get the hd 5770 which will benefit me better (an i agree to that as many other people have said that the 5770 series are preety nice).
