    how badly would graphics be affected if i put a 8X agp graphics card(256ddr) in a 4X mother board? and would it be worth me uprgrading tfrom a nvidia gforce mx420 card to a 256 card?

    It should work, of course only at 4x speed though. 8X cards are backwards compatible speed wise, where you might run into trouble is the voltage requirements. 8X use AGP 3.0 specs which is .8 volts vs 4x cards at 1.5 volts per the AGP 2.0 spec. It would depend on whether your motherboard AGP slot would support the correct voltage. My teenager has a 8x FX 5200 in his motherboard with a 4X slot and has no problems.

    so would i be able to get most of the benefits of a 256 ddr graphics card? The graphics card is a XFX GeForce FX5500 256MB DDR AGP 8x DVI/TV-Out - Retail Box

    you'll probably won't even notice the difference. only way to tell for certain is to have 2 similar systems side by side with 1 a 4x & the other 8x motherboards to see if any difference

    mx420.... pretty much anything is better than that lol :p

    dont worry about it being only 4x board the card will still run but only at 4x.

    the performance would depend on the rest of the system but i dont think it would be that much a difference from 8x as long as you got a decent cpu and ram

    I can't tell the difference.

    I've tried my X850 XT and AIW 9800 Pro in both and I can't notice a difference.

    My Dell has 4x AGP and the other PC has a ASUS P4P800-E w/ 8x AGP.
