[QUOTE="Vipersan, post: 969656, member: 325666"] The optiplex 990 has arrived ..so this thread is dedicated to its use as an SDR receiver.. Just completed the 'ratings test' ...which only gives a score ascociated with the worst component(s) in the system. It is pre installed with a copy of windows 7 pro genuine.. The first thing to note is the SFF amall form factor .. It is even smaller than the Optiplex 620 ...and susopect the foxconn fan is a bit noisy so may need replacement .. It is fitted with Win7 as I said ..but a 64 bit version ... The processor is a Quad core i5 Menory is a substantial 8gb Ratings are as follows .. Calcs per second 7.4 Mem ops per second 7.6 HD data transfer is currently 5.9 ...but this will change as I intend to clone the O/S to a larger drive asap.. The lowest rating goes to Aero .. A dismal 1.0 As is the Gaming Graffix .. Also 1.0 So it is going to need a low profile graphics card ...pcie X16 There are no PCI sockets ...so no extra USB ...not that I should need any with 9 usb as standard Which leaves the 2 pcie slots .. One for a graphics card ..and the other for the TBS sat card .. rgds VS [/QUOTE]
