Unless you're going to be running 4 monitors don't bother with 2 graphics cards...and definitely don't get 8500s. I would also advise not buying from MESH...On paper they are excellent value for money,they use good quality components but their build quality is erratic at best. I used them twice in the past..when the driver delivered it he remarked "See you in a couple of days, when I come to pick it up"...he wasn't wrong! There was bubble-wrap wedged between the Graphics card and motherboard, the case was scratched and they'd installed a different processor.. I'd ordered an X6800 and they installed a Q6700. They did sort it out quite quickly and were immensely apologetic. So I gave them the benefit of the doubt and ordered a second system..this came with the wrong Motherboard and Memory!! Needless to say I haven't used them since. However, it did get sorted and they were actually as cheap as building yourself especially as you do get lots of bundled software..but for me it would have been less hassle to self-build.
You'll find it difficult to get the same system at an equal or lower price...but you may pay for it in hassle, then again you may be lucky and they get it right first time. Either way I would not get that Dual 8500 system!
If you go for MESH then I think this is closer to your needs as you're sticking with FS2004:
