Well it's your business when they post here. Otherwise you're just a yes man "buy the most expensive" lol. If you saw something where it's a bit faster but hell of a lot more expensive, and the person says buying the most expensive one because it's faster, wouldn't you say well you're paying £1000 for 5 fps?
You can save a lot of money by getting a slightly lower spec and it'll be darn close to one above it, and literally you'd be able to buy a another monitor with that difference.
It's quite obvious anyone who is into PC components knows what the premium for the upper range parts are. I bought a Pentium 200mhz MMX when it was VERY expensive. It wasn't worth it.
There is prograssion of scale.
Onboard will not play 95% of games smoothly
Midrange 60fps
upper mid range 100fps
High end will play say 150 fps
If the £ difference is not a lot until you get to 150fps card, and then it's three times the price of the 100fps, is it worth it? I'd say no
Same for HD size, biggest isn't best value for money, work out price per GB. And drop a GB capacity as it's better value for money per GB.
Anyone with more money than sense can throw money at it, it takes a bit more planning and knowledge to determine VFM (and that doesn't mean buying qtec PSU either)
