So a new single rail power supply to power a video card from this list is my advice.
I play alot of games that require a "good" graphics card and my computer isn't running the games fast and i have to turn the game's video settings to "ultra low" or "very low" in order to get a decent framerate.
Examples of games that i play are:
- DayZ (Arma II Mod)
- War Thunder
- (and soon) Battlefield 4 when it comes out
I'm new to most of this stuff so simplified answers will be the best answers
I have an i7 processor
(if theres any other info needed please let me know)
Thank you for reading,
