Intel Pentium D 925
2GB DDR2 RAM 400mhz
8600GT DDR2 512 MB
160 GB Western Digital SATA Hard Disk

Please no suggestions on a new PC, and all upgrades must be tested on a rc410m (asterope 2) motherboard

I would say the graphics card is, if only because it does not support levels of DX that some modern games require; the slow CPU will multiply FPS by some fraction, but in this case the missing capability of the GPU will multiply it by zero.
Even a HD7750 would be a substantial improvement, and should run on a PSU that can power a 8600GT. A card any stronger than that would be too badly bottlenecked by your CPU to be worthwhile. If you want nVidia-based features like PhysX, the closest equivalent is the GTX650.

Thank you, but could you also tell me which is the best card for RC410M motherboard?
 
Judging from http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c00638516-15%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken that is a really old board. The caps aren't all solid, so I'm surprised it's still alive.
I believe the HD7750 will work in a PCIe 1.0 slot. Another alternative would be something like a HD4770 or HD4670, if you can find one.
