That’s the test I was talking about. It’s called WEI (Windows Experience Index).
Your overall note is of the level of the slowest component. Here, the graphical card. Your video card shows a normal average score for a business purposed card ; you “only” have 2 X 256MB ram per gpu.
It does not look like the card is the culprit (apart from the driver “features nightmare” you described before).
I get nearly the same scores you got with my I920 (including on the video department), but I too, am surprised to see your SSD score with a Vertex 2…
I get 7.3 WEI score with an OCZ Agility wich is much slower than your disk.
Maybe It does need a firmware update (some added function come overtime with firmware updates like TRIM).
You should check that under peripheral management/disks, the “best performance” option is checked for the Vertex Agility and that the “use write disk cache” is on too.
Check that the ATA Channel your SSD drive is plugged to is on DMA 5 or 6.
Deactivate file indexing and defragmentation as well for this disk.
I read some users claiming better performances on SSDs with AHCI as well but as Bernard pointed out, it could be marginal.
At last, you still have to check (maybe you did but didn’t mention it) in the Bios to verify your CPU is not throttling.
