Do I need to flash or upgrade BIOS when I change my graphics card?

Do I need to flash or upgrade BIOS? I am just asking out of curiosity, because I read that some motherboards will not support a graphics card if there is no BIOS flash/update. I never done it before, so I will try to stay out of touching BIOS as I know that it is risky to play around in it. My motherboard is DG33M06, and the card that I have now is ATI/AMD/Dell Radeon HD3450 64-bit, and I will be putting in a Sapphire Radeon R7 250 1GB GDDR5 128-bit. By the way, I can replace a 64-bit graphics card with a 128bit one?

Just install only the correct driver for the graphics card.

DO NOT flash your motherboard bios!
At least until you have a problem that impacts you and an updated bios will fix.
A failed flash can permanently brick your motherboard.

The ram and speeds of the graphics cards are irrelevant and have no connection to the motherboard.
From that point of view, you are OK.

What may not be OK is your power supply.
A R7-250 will want a 380W psu:

You might be safer with a stronger and less power hungry GTX750 if you have the usual cheap dell 300w psu.

That's why I wanted to ask before I acted. For the PSU I'm getting SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E168... :) . Thank you for your help :) .
