I currently have a VERY VERY VERY ghetto compaq and have been trying to simply play Black and White 2. I also hope to make BF2 playable - it is choppy on lowest settings; about every 30 seconds the controls freeze in one direction for about 5 seconds, making for one hell of a helicopter ride.
My goal is to get a new graphics card to help hold me over until I'm ready to invest in a new computer. Hopefully I can survive another year with this unwanted bastard child of a 1.6ghz pc2100 400mhzFSB machine. I keep building computers for friends and feel like crying sometimes. Sometimes at night, I think of ending it all and i cut myse- errr, nevermind.
Anyways, I'm looking at the GFX card lists and have my eyes on some 4x/8x cards. I've had my eye on the SAPPHIRE 100131 Radeon X800GTO 256MB GDDR3 AGP 4X/8X Video Card - OEM .
How much power will I lose running this thing at 4x?
Well obviously 8x is potentially twice as fast as 4x but the real question is if 4x is a bottleneck for the card in question. I'm sure someone that is really good at math could get into fill rates and bus bandwidth and give you an answer. Perhaps if I get really bored tonight I'll try to figure it out. I don't think it is an easy question to answer. If the card does not stress the 4x interface than 8x is not going to be any faster.
Well I tried to figure it all out and have had no luck from a math standpoint. AGP 4x bandwidth is 1056 MB/sec but I've not found any info on how much bandwidth is required by any givin card. It is a good question I'll continue to look into.
