Wee Weasley Welshman,
I am running the MSI RX800XT Platinum Edition-VTD256 and I agree it is an incredible Vid Card.
Was it a Birthday present for you? Btw, Happy 30th Birthday.
spannersatcx,
The best bang for the buck is either the GeForceFX 5900XT 128Mb or the Radeon 9800Pro 128Mb. There are no issues at all running them on the ASUS A7N8X-E Deluxe. Till my recent upgrade to the MSI K8N Neo2 Platinum mobo, I ran the A7N8X-E Deluxe. It is a great mobo and works flawlessly with any modern Vid Card.
Take Care,
Richard
