Ok Guys, this post will be FULL of any q's i can think of. I'm looking to get a new video card...peferably for less than 100 bucks, but of course, it all depends on whats out there...and i can't know if something else is worthy of the few extra bucks if i dont know a thing about video cards =( So it begins: (and feel free to skip questions if you dont wanna answer all of them) 1. Chipset Manufacturers The Big Guys. A. Whats the advantages/strengths/weaknesses of ATI and/or Nvidia? B. Are there usually compatibility issues associated with them (i.e., if i have AMD dual-core or Intel dual-core, will either one work better or worse with ATI/Nvidia?) C. With similar performance, how does each of Nvidia/ATI's products price match repsectively to their competitor? 2. Manufacturers The ones who make your cards. A. We all know the big guns ATI and Nvidia...but what about the manufacturer...does the manufacturer really make a difference in the big picture? 3. Slots Determines what type of video card you must buy for it to fit. A. What's the typical slot type for the latest computers? B. AGP vs. PCI-Express...sure, if you already have your computer, you can't really choose between them, but...besides being different forms of slots, what the advantages and disadvantages of each? C. How big is the difference between AGP's 4X/8X/PRO4X/PRO8X? PCI-E x1/x16/x2.0? Is it major enough to consider upgrading to the next step? When does the upgrading factor begin to depreciate? 3. The Specifications We all know the more powerful the GPU the better, or the higher the memory, the better, but how about the specifics... A. THE GPU The Core clock 1a. At what point does the increased performance begin to depreciate with the highly increasing prices? 2a. How big of a difference does a higher core-clock make? (ie, 500 Mhz to 600 Mhz) 3a. How important is this compared to the other technical aspects of a video card? B. Memory Size 1b. What is the typical minimal memory size needed today for a video card to run some modern to new games at with a fairly good FPS and/or for casual gaming? 2b. How much of a difference will upgrading to the next level up make (ie 64 to 128 MB), disregarding the obvious fact that it depends on the graphic intensity of the game 3b. At what memory level does the memory start to not make any real noticable difference? 4b. Whats the minimal that you should get for any hope of playing some somewhat modern games? 5b. How important is this compared to the other technical aspects of a video card C. Bus Size 1c. What is it? 2c. What's the standard for somewhat-modern gameplay? 3c. At what level does bus size start to not make any sort of noticable difference? D. Pixel Pipelines 1d. What are they? 2d. What's the ammount i should shoot for with for casual gaming with modern to newer games? 3d. How important to this comapred to the other technical aspects of a video card? 4. DirectX A. Should i go with a DirectX 9 or 10 if i have an XP Pro system? 5. DVI A. What is it? B. How Essential is it? Ok, thats all i can think of. Sorry if some things are the same and are simply interchangable terms...i am learning, and i'm sure this info could be of a lot of help to many newbs like myself. Thanks in advance!
