I wont sell my 5830, it will go into my HTPC, but I get your logic. Plus with a 5870 I have more headroom...I could Crossfire it down the road when my CPU is ready for an upgrade. This is the route I am leaning towards. I effectively get 3 GPU upgrades by cycling hand me downs to each of my computers and I have room to grow next upgrade. Plus, call me lazy, I dont feel like swapping the PSU and Mobo until I get my next case.
