Guys can you give some advice about upgrading my Gaming Rig?
Did MSI N560GTX-Ti OC 2gb Ddr5 Twin Frozr will be compatible with my P5SD2-VM Mobo and 450 Watts PSU Non-Branded with 4Gb DDR2 533, a old E5200 OC at 3.6 Ghz, Windows 7. Will i run most latest games on Ultra 1920x1080 res. with this Setup?
No, it is not compatible simply due to not having a strong enough PSU. You'll need a 600 Watt + 30 amp rail/s to handle. Otherwise, the rest of the components are fine. You'll probably see most games on High settings, some maybe on Ultra with that res.
