What are the differences in Video cards?

Such as PCI-E A series, PCI-E N series, AGP A series, etc?

How do I know what will work with what?

PCI-E and AGP relate to the interface on the motherboard that the card fits into.

AGP is now a dated tech that you probably won't see around anymore.

PCI-E is what you'll be looking at these days on almost every motherboard.

The A and N after the interface type relate to whether it's ATi or NVidia Technology in the card.

So overall, you're looking at PCI-E cards for almost every motherboard I know these days. It's then down to what you want from your pc to whether you go Nividia or ATi. For example, not all boards are certified for Crossfire or SLi, so say a board was only certified for SLi you wouldn't be able to run 2 ATi card in it only NVidia ones instead.

Hope that helps dude. Anything else feel free to ask.

WOW, That is a BIG help! Almost as if a legendary London fog had just been cleared away!

Now all I need to know is What or why ATi and Crossfire and SLi are and I should be able to rattle it off like you just did!

And then....do I need any of that???

Thanks a BUNCH!!!

ATI are the competition to nvidia, crossfire is 2-4 ati cards in 1 system and sli is 2-4 nvidia cards in 1 system. 2 cards you usualy get an ok to good performance increase, 3 not much over 2 but some games suport it well, and 4 very rarly gets a boost and sometimes lowers performance over 1 or 2 cards. 3 or 4 cards are mostly for e-peen or benchmark scores.
