  1. Hard to say...

    Some people have reported problems in general with a PCI-e 2.1 card in a PCI-e 1.x port. Check Asus' site for a BIOS update.

    Otherwise I would simply spend a little more money on a HD 5850 PCI-e 2.0 card to avoid headache which includes spending good money to send back a HD 5830 PCI-e 2.1 for a different card.
  2. yeah you see what it is, is that im trying to keep the budget spend as low as possible.

    http://www.overclockers.co.uk/productlist.php?groupid=701&catid=56&subid=1711&sortby=priceAsc

    all of these are apparently 2.1 so any suggestions on a good budget gpu thats 2.0?
  3. http://www.asus.com/Motherboards/AMD_AM3/M4N68TM_LE/#download the first bios release was 2009, so it should support pcie 2.1. Incompatabilities exist with older bios's only. A 5830 is rubbish anyway (power hungry crap) , much better off with a gtx460 of some sort.
  4. I would call Asus tech support to find out if the latest BIOS will support a PCI-e 2.1 card in a PCI-e 1.x slot.

    If I was me I would bite the bullet and simply by a PCI-e 2.0 HD 5850 card. Maybe I would stay home one Friday or Saturday night to save up money for the difference.

    :P wish that was an option but im only 16 and i got like 9 important exams coming up in 2-3 weeks time. but i will consider 5850 as an option.
