I have this PSU Newegg.com - LOGISYS Computer PS550AC ATX12V 550Watts Power Supply 100 - 127V/200 - 240V CE, FCC, CB - Retail
and I finally have enough money for a new GPU do you think my PSU could handle this one Newegg.com - SAPPHIRE 100225L Radeon HD 3870 512MB 256-bit GDDR4 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
with that card would I see a big improvement over my 1900GT? Is there anything better for the same amount? Also it says PCI-E 2.0... What is that? obviously I haven't been saying up to date like I usually do lol.
