I've received help from some peeps on the forum with a new setup and i've narrowed it down to the spec below. The only thing that i'm confused about is the gphx card. I initially chose a £25 item with no intention of gaming, but someone recommended spending more like £60, and now i'm thinking about spending more and giving myself the option of playing games if need be. No first person games, maybe flight sims or racing games. I've been reading the 8800 GTS 512mb is the way to go for the best but i'm thinking this is too much money and probably a bit of a waste for me who's primary use is internet followed by video editting. The 8800 GT 512mb is £130 and probably getting closer to where I am, but i have no idea of how powerful a gphx card is and what it can do as my last buy was an Nvidia Riva TNT2 and i never really used it for what it was intended. I want this setup to last 5years btw:
Any help much appreciated!
