Hi I have been watching films and video from my PC to my 32in TV with a SVGA connection but my on board graphics card will not allow me to increase my resolution to 1080p without juddering/skipping.
I have found a Graphics card which has great reviews and would like to install in in my unused PCI X16 v1.0 slot
Will a PCI Express XFX ATI Radeon™ HD 5450 graphics card 2.1 work in a PCI Express Bus specification v1.0a compliant.
My PC is a emachine E4036 Pentium 4, 3.2ghz with 2GB Ram.
Thanks Geoff.

No your motherboard is likely to old to actually support 2.1

You may have issues. Some people have reported issues installing a PCI-e 2.1 card in a PCI-e 1.x slot.

In some cases it seems to have been resolved with a motherboard BIOS upgrade to fix the potential issue. But brand name computer companies do not usually provide BIOS updates often, if at all.

Your best bet is to buy a PCI-e 2.0 HD 5450 like the following for $35 after a rebate. Just be aware that it is really to weak too play modern games if that's the goal.

Thanks for the info mute20.

I will now rethink.
There must be something better than the on board graphics card with a bit more power
that will slot into my empty PCI Express v 1.0 slot to give me higher graphics.
