Can't go wrong with the Lightning if you can still get it around 1.2k-1.3k, what's your PSU though?

Are you going to overclock this beast?

What is the rest of your system? Your PSU is sufficient for a 290x imo.

Nah, your PSU is fine. The Lightning power consumption is similar to other aftermarket 290x.

PCPER Lightning test system only use 412 watt of power on load with 3960X processor.

Tomshardware tested the card only use 258watt average on Heaven benchmark loop with some occasional spikes to 400+ watts. Your PSU should be able to hand those. Even when overclocked to 1150mhz the card only consume 272watt on average when gaming.

Now near the end of January already, if me I'll wait for 300 series. Your HD7870 still can play latest games too.

If tak boleh wait better for for cheap GTX970... (lol i know it's Radeon subforum) or get a 2nd hand r9 290?

If you plan to run with high resolution multi-monitor setup, it'll be worth it. However for 4k & higher resolution, you'll need more than one card to get nice fps though. If you plan only single monitor, 4GB is more than enough. I'd get 290x lightning. Your PSU is enough for single card.

Of course

290x dirctx 11
970 DirectX 12

Anyway I will buy lightning

Unless you're going to CFX them, 8GB is pretty useless imo. Unseen83 play at 4K res with 2x 4GB 290x CFX and he don't have problem with the 4GB framebuffer... i think.

If you plan to run with high resolution multi-monitor setup, it'll be worth it. However for 4k & higher resolution, you'll need more than one card to get nice fps though. If you plan only single monitor, 4GB is more than enough. I'd get 290x lightning. Your PSU is enough for single card.

To me is depends on the PCB & cooler design, for example if Gainward/Leadtek GTX970 vs 290x Lightning, i definitely will choose the latter, but if gigabyte windforce gtx 970 vs 290x lightning then i might choose the former. I personally like full length PCB & big cooler, it look great inside the casing (provided your casing has side window)

290x will support DX12 just maybe not fully support it.

Not fully means not supported. Who wanna buy a card now that does not support dx12 ?

Totally expected since Microsoft haven't finalize DX12. There's no card in the market right now that is "fully" support DX12.

Sucks for 290x owner

Well, another 380X news anyone?

@@ and nvidia still lansi about their 'low power' gpu

if you got 4K lcd go for 8GB VRAM   if Vram so important to you wait for R9 380X... HBM  haha  but  on my 4K lcd with 2x R9 290X vapor/Trix..  all game play 30Fps +  some game even got 55FPS  when AA is off...  but i got no exp with 8GBVRAM... but if i hav money yeah i get 8GB vram gpu lolX

frankly, low TDP hardware works best if
1. youre building mITX system where cooling is a huge concern
2. you actually cared of the savings per year from using less power hardware
3. youre on a mobile device

but were on a desktop, power consumption shouldnt affect us that much (unless youre extremely sensitive to minor changes in electric bills)
IMHO, impossible. im on a GTX780 that was supposedly overkill for 1080p. yet im getting fluctuating frames on games that i should breeze through (no, im not even CPU bottlenecked yet)

the only way for you to confirm a solid 60FPS, is to lower graphical details. dont even think of touching AA settings unless you want to see plummeting frames whenever a graphical intensive scene appears

and dont be too fussed on 290X's power requirements. i OCed my GTX780 quite high even with a 650W and my PSU isnt even struggling to juice it up. you rarely see GPU throttled by lack of power unless you deliberately feed it lack of power

you dont need a 1000W

even a solid 850W Gold is good to go for dual CFx/SLi setups

the 620W is fine, just use it first. if you started encountering lack of power symptoms then only you upgrade. (ie. PC shutdown while under intense load)

just do a little test before making PSU purchase. plug in new card, run Furmark for 15mins. if it passes that, you should have no issues already.
this is not applicable for all scenarios

most 3rd party GPU coolers like Strixx, Windforce, Twin Frozr are already pretty quiet even under heavy load at 70% fan speed (you dont even need to ramp up speed cause its damn efficient already)

when idling, theyre on 0db mode as well. if you can hear noise from that, its either electrical noise from the parts or your case fans

only when during reference cards is where higher TDP might equate to more noise. but frankly, i dont even find my 780 at 50% noisy. only when i ramp up to 80% is where i consider pretty noisy.

tldr : GPU coolers these days are pretty efficient to the point they can dissipate even 300W of power with no need to spin fans at 6k RPM (cept AMD ref cooler, that thing is just plain bad)
