I have a radeon 6450 but i want to play games like black desert online or crysis 3. Gpu's i want: MSI RADEON R7 250X 1GD5, MSI Radeon R7 250 OC,2GB, ASUS GeForce GTX750-PHOC-1GD5 - 1GB - PCI-E, MSI GeForce GTX 750 1GD5/OCV1 - 1GB - PCI-E or the MSI GeForce GT 740 - 2GB - PCI-E. Which is the best choice for me?
Additional information: i have an acer aspire x1900, Sith a Pentium dual core e5800 3.2 GHz.

Your PSU has an EXTREMELY low wattage and hence I would only suggest you don't buy a gpu until you can change that. even a 65w r7 250 will struggle with your PSU.
