Is that all you need to know other than i think i have only 300 watts but could i jump up from a ATI Radeon HD 5450 to like ATI Radeon HD 6350 with 1GB SFF DMS 59 cause to me I'm no technical person at all.
If you want to play games get a new power supply and a Radeon 6850/Nvidia 550Ti or better or if you want to keep the power supply a Radeon 7750 or 6670. I think a Radeon 6350 would be integrated. If you want more help what do you want from the card and whats your budget?
The Radeon HD 6350 is an under powered video card mainly used for basic needs like watching videos and movies. It is probably just as slow as a Radeon HD 5450. The price range of the HD 6350 from $56 to $92 simply boggles my mind.
If you want an inexpensive graphics card to play games with a 300w PSU, then consider the following HD 6670 for $55 after mail-in rebate.
Click the link below to see benchmarks for the Radeon HD 6670. The test rig uses an Intel i7-920 clocked at 3.8GHz.
Also, if you increase your budget to $110 you can buy the recently released Radeon HD 7750 which provides better performance than the HD 6670. However, the HD 7750 is 2x the price of the HD 6670 I linked to in my previous post, but the average performance increase is not 2x.
