GX620 is too slow for even 1024 X 768 GAMING with Pentium D. All gpu's are crazy expensive now. This system is 15 years old now. Your money is much better spent on buying an Optiplex XE2 with windows 10 and then waiting for GPU prices to come down around 1 or 2 YEARS from now. What you are asking is not possible with something that old. [URL] Even when a GTX 1080 ti is put into a model like this its Horribly slow. [URL]
