Need opinions on these Driver Update sites....

I had Windows XP and upgraded to Windows Vista (32 bit) after a trojan had infected my computer. There's a lot of drivers I need to update now and the one I'm mostly concerned about is my Video Card driver, I just have the standard video card that came with my computer since I like the older games, so it's not a big brand name card and the driver is ridiculously hard to find.

So I've found these 3 sites that claim to be able to update all my drivers:

http://downloadpcdriversupdates.com/drivers/video_...

http://www.driveragent.com/?PHPSESSID=jlpvji9qppnc...

http://www1.uniblue.com/products/campaigns/ppc/ds/... driver|1513544948&gclid=CIiyhtTR7pQCFSEbagodaHoMrQ

Each site of course, typically claims its free blah blah blah, allows me to scan my computer then wants me to pay $30 just to update all the drives. Is that really worth it? There's got to be an easier way to get my driver updates...

$30 is ridiculous.....

I really need some recommendations on this, I just want to get my video card driver updated so I can get back to the video games but at this rate it looks like I may just buy a freakin $200 Video Card.
