asus A7N8X or msi K7N2-L???

i'm gonna get myself some new hardware and i've been looking at the posts here for some days now. but i cant figure out wich one to take. the A7N8X (non deluxe!!) or the msi K7N2-L. they both have about the same specs and the msi is cheaper. and why is it exactly that the 2500+ barton is faster than the 2400+. the 2400 has a speed of 2.0 Ghz but the 2500+ 1.83 Ghz ... so how does that work? is it becus of the larger cache and the faster 333 fsb?

anyways this is what i'm thinking:

amd 2400+ or 2500+
asus A7N8X (non deluxe) or msi K7N2-L
wd 80 gig 8 mb cache
2x 256 mb ddr333 kingston
400 watt dual fan gold ps (q-tec)

than i still have an asus geforce 2 64 mb MX400 which i want to keep for a short while. do u guys know if its compatible with the mobo? hope u can help me out here. any suggestions on something else i should take r welcome too.

1. Get MSI K7N2-L.
2. Get 2600+ at 333FSB. There is no big favour for 512K cache on 2500+ to 2400+ but 333FSB do faster then 266FSB but IMOP 2600+ is a better solution. All Barton core Athlon XP are clocked at lower frequency because AMD think that the large cache can cover the performance loss.
3. You GeForce2 MX400 will work just fine on your new system unless it's a PCI version.

My PC has gone to hell... because it's a killing machine...

i got another q. conserning the asus A7N8X... in the manual it seems it only supports dual channel ddr with ddr400. is this right or will it work with any ddr...? btw thanks for the replys

ok guys this what i decided:

asus A7N8X (non deluxe)
amd athlon xp 2500+ barton
2x>> kingston hyper x 256 mb ddr370 cl 2>>2-2-2-6-1/or2-3-3-1
wd 80 gig 8 mb cache
q-tec 400 watts dual fan gold

now i just have to find a good site either in belgium or holland.i'll let u guys know how it works out.

thanks
