I don't know you, changed your mind. But we don't know the price yet anyway only for the Founders Edition prices have been announced which always command a premium. I'm still sticking with my initial estimate. TBH I think many gamers will be disappointed with the performance uplift over Pascal cards and won't update their cards and wait for the 7nm refresh next year. I certainly won't be updating.
Um....the GTX 2070 looks like it will retail for around £550, and will likely give you around the same performance as the 1080, you paying £65+ less and getting a £100 PSU with this. So not sure if you are joking or not, because the new cards not being at a good price is the one thing most posts I've seen about the new cards seem to agree on.
Such a good price!? Go look on the Nvidia website: Founders edition 2070 is listed at £569. So I don't know how you can say that's cheaper. Scan has AIB 2080 cards listed at over 1K. So you know an after market 2070 is going to be easily over £600. Also, there was no mention of raw performance of FPS Vs the current gen so, ray-tracing aside, we're still to see how much more powerful they actually are.
Cheaper? Have you seen them for sale anywhere? I've only seen 2080's and 2080ti's seeing as $699 and $999 have translated to over £700 and £1000 it seems unlikely the 2070 will be less than £500 whenever they become available.
And with the new cards out at such a good price this is now the worst deal ever! do not waste your money om a 1080 when the 2070 is cheaper still and way more powerful.
