For simplicity, I will just link you over to the thread I am participating in at HP... but short version - this system is only a few weeks old so it IS the new system.
After much discussion with HP, the nForce 720a motherboard DOES have PCIe version 2.0 slots. So I have already purchased and am awaiting delivery on a new 650w Thermaltake PSU and Radeon 4890 GPU.
We'll see how it goes.
PS - Aries, yes, I slipstreamed the drivers. But I had to use one set of nVidia drivers for the SATA and another set for everything else. Don't know why.
