Hi, I have a Pentium dual core E5400, 2.70Ghz. Since I have no graphics card and I am on a very tight budget, I was wondering if MSI GeForce GT 730 2gb GDDR5 would work on my P.O.S. 250w Dell PSU. My system is a prebuilt Inspiron 545 that has had the CPU changed to Pentium dual core E5400 and ram changed to 2gb DDR2(some guy scammed us) And if it works, what type of gaming can I do with it? Thanks in advance.
