My first reaction is to upgrade my PSU and get a more powerful graphics card, but i'm not sure if that's the best, considering my weak processor, and older mobo. I think a more powerful graphics card would be severely hindered by the dated parts, thus making the investment a waste, but I don't really know for sure how that works.
Yes, you may benefit from a new PSU (power supply unit) . But why do you think so? Apparently you put in a graphics card and did not upgrade the And why do you have 8GB? And how do you measure oomph
anyway? Are you using a 64 bit OS? And do you have 64 bit games?
When your machine was new out-of-the-box it already was a major player in the store-bought computers. Apparently Dell though is was good enough to support more drives in a RAID. So the PSU must have been enough for that. RAID would have increased performance overall.
Only a few extreme games benefit by a 1 GB graphics card.
You wanted an answer, so there it is. One does not need a better PSU until there is proof that it is failing.Bigger is not better. And lthe are not bigger anyway. Same size. These are switching PSU;s. A lot of the ____ people write about PSUs have nothing to do with switching PSUs. They don't understand how they work. If the PSU is getting air flow, it will work and work until there is a persistent overload, at which time it will turn you computer off. That is how there a e made.
When a PSU does shut down, it is often due to some component the in system fairing, not the PSU itself.Going to a bigger PSU, in such a case, is not the right answer.
As you can tell, I get really ticked off when people say 'you need a new PSU well there is not proof that it is the issue.
If you want more power, unplug the floppy and the DVD drive and any USB powered gadgets while playing a intense game. IMHO.
