friend is offering me nvidia 9800gtx+ for $150

ok, ive instead decided to go with this one:
Newegg.com - MSI R4830-T2D512 OC Radeon HD 4830 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards

it looks like it gets almost the same performance as the 4850, but for 90.
