A bit torn right now. I have a new rig essentially planned out already, but the motherboard I was originally planning on, a GIGABYTE GA-EP35-DS3L is not PCIe 2.0 compliant.
Now, I know 2.0 cards will run just find regardless, however, I will likely upgrade from my current 8800GTS 640mb to one of the 9x series in the future which I've been reading may max out the throughput on PCIe1.0/1.1 and leave me a bit bottlenecked.
The GIGABYTE GA-X38-DQ6 users the x38 chipset which supports PCIe2.0, but it's also about $110 more expensive. I also can't find terribly many reviews as to the quality of that board in particular.
Bottom line, should I spend the extra money and go for the 2.0 board, or am I worrying too much about this? Technically I could just swap out boards with a 2.0 board in the future when I decide to get a 9x, but I'm lazy and hate having to yank the main board out unless I'm doing a total overhaul.
All right. Before you buy the DS3L, check out the GA-EP35-DS3R too. $38 more (Newegg current prices) gets you 8 SATA ports instead of 4, more cables, eSATA, RAID. I have no idea if that's worth $38 to you, you decide. For me having only 4 SATA ports is a problem.
