(hope this is the right place to post this)
Need some advice about a graphics card upgrade.
I currently have:
AMD Athlon64 x2 Dual-Core 4200+
2GB DDR2 Memory
(Galaxy) Geforce GTS 250 1GB DDR3 Ram
HP Compaq Presario sr550p1 (w/250 watt PSU which came with it)
I just bought the GTS 250 and i'm for various reasons not happy with it.
It seems to actually be worse playing certain games like GTA IV than my old (now dead) evga Geforce 8800 GT (Superclocked) 512MB DDR3 - which is kind of strange.
I would like any advice on why this might be, but more importantly i'm curious to know if it might be a good idea to just return the card and pick up the XFX Radeon HD 4870 1GB DDR5 card (http://www.amazon.co...66300615&sr=1-1) - it is the same price as I got the GTS 250 for and passmark rankings suggest it is MUCH better.
My only worry is it might be a bit too thirsty for power, my current PSU probably couldn't run it (probably can't run the current card) and so i'd need an upgrade but i'm hopeless at hardware stuff and would have no idea what to get, or what i'd need. Some review reckons it needs dual 6-pin connectors, I don't know what that means! Does anyone know if my current PC would benefit from this change (getting the Radeon) and if so could they suggest to me a good PSU for it please?
Thanks in advance for any help
