is it worth it to upgrade?

[onedestinazn2]

i currently have a gigabyte p35-ds3r rev2 with a e2200 but someone around here wants to sell me their abit x38 quad motherboard for $80. i know that my cpu is a little dated and was going to upgrade that first but the ability for crossfire seems so hard to pass up even though im gaming at 1650x1080 with my 4850. also if anyone with the abit board could tell me how's the quality of it?
