You see some higher-end (supposed) PSUs these days touting "Japanese capacitors".. The issued had to have been significant for some...
2 computers. i'm now using an ATI 5750 (1 gb ddr5) and it's super quiet and runs very cool. the trading rig is now used for games
whatever you decide, i advise to stay away from Dell. Everything I ever bought from them (compared to other makers) seems to wind up slowing down, regardless of maintenance, cleaning or even reimaging the system.
I've had Dells almost exclusively for the last 10 years.. currently have 5. All running perfectly, without a hitch, fast as ever.... just like when they were new. However, I don't buy from the budget lines.. like Inspiron, Optiplex, Vostro. The problem you have with Dells most likely... IS YOU!
LOL! We have Dell fans, HP fans, Apple fans. Intel fans, AMD fans... The latest trading computer brand I use is the Bolimomo brand. And I love it! LOL
I have a bunch of Optiplex, 755 Small Form Factor x 8... Love them!! Also: 2x Precision 490 3x Precision 690 2x Precision T3500 1x Precision T5500 3x Precision T7400 2x Precision T7500 Amazing all and all, but you may feel otherwise
