i want to upgrade Dell optiplex 9020 (i7 3.5Ghz,16 Gb RAM, 500Gb 7200RPM Harddisk, Power supply 290W) with AMD Firepro W7000 Graphics card. Dell people told that thay didnot test W7000 on Optiplex series so thay don't know if it will work or Not. I also want to know, should I go for AMD Fire ProW7000 or Fire Pro W5000 with SSD dard drive. I am using SolidWorks 2011 and buget is approx Rs 50000 ($800).
The video card will make very little difference. Stick with the cheaper solution. I even suggest the V4900. Especially with a 290W power supply, there is no guarantee the W7000 will even work because it uses quite a bit of power. It requires an additional power connection.
The SSD will make a huge difference, if you want to upgrade a machine, that is the first thing I would do.
