|I check the Dell driver download page by my service tag and it has it as "AMD - Radeon HD 5770". If I check Device Manager, under "Display adapters" it says, "ATI Radeon HD 5700 Series".|
The reason I started updating video BIOS is because sometimes screen would freeze unexpectedly and I had to reboot computer by holding power button. I then went to the Dell driver download page and it had BIOS update for that card marked as "urgent".
So, thanks for the benchmark results, and even though it's not an exact match for the ATI card, I see that it's much better then the nVidia card.
