Because it's £40/$50 more. It's not rocket science, more is more, and in this case some people may find a price hike of 25% for a 5% increase in performance (and an unknown increase in the future) to be too much.
Its not rocket science,VRAM limited cards have shown much less lasting ability over normal versions. Hardware enthusiasts on forums who make arguments for the following cards,all went quiet when the cards hit issues:
1.)8800GT 256MB
2.)8800GTS 320MB
3.)GTX460 768MB
4.)HD3850 256MB
5.)HD6950 1GB
6.)HD7850 1GB
Probably a few others too which I missed out.
I knew mates who went with those cards due to the "its enough VRAM" brigade and regretted they did not pony up the extra cash.
Its more expensive to buy a new card.
Those enthusiasts on forums made them waste their money.
There has been plenty of evidence,to show those cards and this card have big issues when they hit VRAM limits.
EVERYTIME these sorts of cards are released,people go on how perfectly fine they will be,and almost everytime they don't last as long. OFC,being the internet people conveniently forget cards,and then restart the same thing for the next round.
People keep cards for years - two to three years. £200 is considered the start of the "enthusiast" pricing range for cards. £200 is the sort of money which buys who a Core i5 6600 or a 6600K,and only people buying decent rigs have those sorts of CPUs.
I have not met anybody in 15 years who could spend £200 on a card,could not find £230 for a better card.
People who generally are that tight on money,tend to be people buying £100 CPUs like a Core i3 and £100 to £150 cards - this is what the GTX750TI,RX460 and GTX1050 4GB are aimed for.
"
Those who cannot
remember the past are condemned to repeat it."
I suspect once these cards hit their VRAM limits,if anybody points it out,I suspect they will be accused of being unfair or calling out or something else.
Its going to be so interesting to look back at this thread in another year to 18 months time.
