Wael Mahmoud :
Thanks Photonboy for your reply,
Very nice site you sent me .....It is just what I needed(to put cards aside each other)
But I still have few questions ;
1-For future proof 1080p gaming is 580 is enough and 1070 is an overkill ? or should I pick the 1070 to be in the safe side ? (I won't be able to upgrade for the next 3-5 years at least)(I won't use monitor more than FHD--no 2k or 4k)
2-Should I wait for VEGA ? I am afraid of waiting and after that it will be over-budget(HBM2) or comes out very late .
3-Does 580 has any problems so far ? (like 480 had)
4-For AMD card which is better MSI or Sapphire?
5-Does Amd close the gap between it and Nvidia in terms of heat-power consumption-Driver support and build quality ,or not ?
I would like to buy in a month .
1. Really no such thing as "overkill" when trying to future-proof. Games will get more demanding. That doesn't mean the RX-580 won't run all games at good visual quality over the next several years, though you will have to tweak the settings to optimize FPS vs visuals for any system (even a GTX1080Ti) for demanding games.
2. I expect VEGA to be in limited supply and way over-priced for at least two months after physical products can be purchased. And yes, HBM2 should add to the cost so I'm not expecting something of SIMILAR performance to a GTX1070 to cost the same or cheaper.
3. No. The RX-480 issue was only the reference blower style which had a power issue (which could actually kill lower-end motherboards). That's a non-issue now, and for the reference card it was corrected in the AMD video driver.
4. Not sure. I suggested NEWEGG as a guide to look at feedback. Quality is the main issue IMO. I like the Asus Strix cards (for all recent AMD/NVidia GPU's). MSI does make excellent cards to though there are probably CHEAPER versions that may or may not have any issues.
5. Uh... build quality is related to the companies like Asus, Gigabyte, MSI etc. and also varies by the individual card designs. NVidia is much more power efficient (currently), though a good cooler like Asus Strix on an RX-580 can still be fairly quiet. Do remember that POWER DRAW is equivalent to heat dumped into the room so if your room gets hot avoid AMD (up to Vega).
NVidia does tend to have better driver support IMO. AMD has closed the gap however, and later DX12/Vulkan games should be less dependent on driver optimizations.
Other:
Some of the Gigabyte cards are prone to bend/break as the metal shroud is far too thin.
Personally, I would look at the GTX1070 cards, and the following link shows what I mean by looking for quality:

Note that out of 157 people, 88% gave it a 4/5 or 5/5. There was 11% that gave 2% or lower. If you click on some OTHER products you may see 20%+ that is 2/5 or lower.
(ignore scores that have a low number of people as that can be statistically pointless as well as it may be a new product that hasn't had a chance to show FAILURES which can be delayed)
