OK, like most people I bought this to replace a failed graphics card in an aging PC (Dell Inspiron 530). It and many others can be notoriously difficult to buy for due to compatibility issues with newer graphics cards so before buying I checked the web for advice (definitely worth doing BEFORE buying!).
On receipt it slotted in perfectly and on boot up it did exactly as expected, BIOS fired up then nothing!! Fortunately I'd read that there may be compatibility issues between the graphics card and system RAM in Windows XP 32-bit OS. Sure enough if I removed 2 out of my 4 RAM modules (2x512Mb) from my 3Gb of system RAM the graphics card worked fine. I think maybe XP cannot cope with more than 4Gb? Anyway, less system RAM but much more graphics RAM and I've not noticed any slower performance.
All this was rounded off with the latest graphics drivers from the EVGA website that loaded a treat (and of course more up to date than that on the accompanying CD). All now working fine so 4-stars, perhaps should be five as I don't know whether the problems I encountered were due to EVGA/Nvidia or Microsoft but at least it's keeping my old PC going for a little longer!!
