It has trouble running new games, so I have advised him to spend some of his hard earned money delivering mail, on buying some new parts before his birthday (October) after which he will buy a new computer.
Initally it would seem to me that it only needs a new graphics card to give it a few more months worth?
Giving him a few different cards to choose from (HD6870, HD6950 and 560-Ti) he chose a MSI 560 TI TwinFrozr II graphics cards.
I fear that would require he has to get a new PSU?
The current one is a 460W Delta Electronics DPS-460DB A rev. 02F, Alt. P/N: 5188 2863.
