What is the best PCI Xpress card for a Hp Pavillon slimline?

Hmmm, if you have a PCI-E most should fit, where a problem may come is the bigger boards that require extra power supply. They are both long as well as may need a bigger power supply. They also generate a lot more heat in a small case, so you need to be very, very careful here. A slimline case lacks the space for good airflow which is usually needed on a gaming rig. You might consider replacing any standard cables (IDE) with rounded cables which could free up some space for air. They sell them at any PC store, even CompUSA for example.

My suggestion would be to narrow down a small list (2 ATI, 2 Nvidia) of cards you want, then go find the specs to be sure they will fit. Hopefully, and I assume so, the space under the card is empty, if not 2 spaces, so the card can breathe. Most manufacturers should list length and width, if not many review sites will.

 

Your chip? Onboard video on your PC is probably 256 megs, that is pretty standard nowadays on a decent video card. There are some with 64-128 megs you can buy, but you wont see them for what your looking for, it would be a downgrade. The onboard video you have is solo, so if you get a 256 meg card, you can not share the memory. It is weird, basically video memory is proprietary, it is on the card and thats that, unlike computer RAM where you can add and subtract memory. Hope I answered everything, if not, or anything else, dont hesitate. Trying to simplify the best I can

 

Video card? No, if your gaming, 256 megs or nothing. Most 64 and 128 meg cards are on older, slow cards. 256 all the way brother.

 

Oddly enough I just added a card to my wifes Emachines and it automatically detected it. BIOS have gotten smarter, but if you know how to do it, then by all means, yes, disable it and shut down, then add in the card.

Interesting choice of video card. Good reviews for games, great price and even found a review that compared its smaller size to its rival GeForce 6800:

It also compares its size to other ATI cards, a great read that I think will make the decision for you.

I dont think you need us, your on the ball I think your in good shape here.
