DRIVER ISSUES

Hi, I just got 2 new video cards and installed the drivers from the
internet instead of the ones on cd(box).
I was expecting a great improvement over my onboard video card, I mean a
huge difference but no, it's faster but just ok.

Do you think I could get better performance from the actual manufacturer
drivers instead of the generic ones.

BTW, the cards are Visiontek 3650HD 1GB and Sapphire 2600HD 256MB both PCI
express.

As a curious note, the 2600hd is performing at a higuer rating according to
vista index.

The box drivers were v7.9 and v8.2, the download was v8.5.



TIA

Try running a benchmark like 3DMark06 to see the differences...the Vista
Index is meaningless in this respect. You should be using the latest
Catalysts d/l from ATI/AMD. The HD3650 is the superior card and running a
benchmark that tests the card will show this more clearly (actual gaming
framerates are preferable to a synthetic bench, but 3DMark06 but it's still
a valid benchmark to compare videocards same CPU/Mainboard/Memory when only
the videocard is different).

I went to a website showing the 2600 with dd3 to be superior than 3650 on
all benchmarks(except cinebench) even with the extra memory:

I guess memory does play a big deal on graphics.

Thanks.

Yes, it makes a big difference. DDR2 to DDR3 on the HD3650 is 800Mhz
difference. DDR3's overclocking headroom is way more....you can easily get
2000Mhz from the stock 1750-1800Mhz DDR3 clocks. You'll be lucky to get
1100Mhz without artifacting from the 1000Mhz DDR2.
