GTX 960 or R9 280(x)(5) for 450w psu

[xzyzer]

So I have an Antec 450w PSU, and I will upgrade if needed but I'd rather not, (I sound like one of those people I know) which would be best, GTX 960, R9 280/X or 285? I have a 6300 dont plan to oc. or just wait for the 300 series cards from AMD (if they get released this century)

Gtx 960 is the only card that meets the power requirement. If you don't mind changing power supply, 280x > 960 > 285.

Out of those three... the 280X would give the best performance...

Next would be the 960... then the 285... and last would be the regular 280.

I have the 280X because it comes with a full 3GB of VRAM

 

[xzyzer]

Well I may want the 3gb of vram beacause Titanfall, and GTA 5

If I am correct, the 280X exceeds your PSU, and the 960 will cut it close (50W to spare on the 960, the 280x has 750W reccomendation)

Actually, the 280X has a 500W min... and needs 750W in Crossfire...

I had looked for a place that said that, but every card I looked at said 750W and 1000 for CFX. I am sure it can run fine on a quality 550W power supply, as long as it has the required connectors.

I think it also depends on the manufacturer. I have a Gigabyte 280X and the instructions clearly state it needs a 500W min.

Planning to buy a Gigabyte WF R9 280X. Which PSU you would choose among this below with the possibility of overclocking the GPU.

+12V specs:
CM CX600 V2: 40A @ 480W (3rd tier)
CM Thunder: 47A @ 564W
CM G550M: 42A @ 504W (3rd tier)
Thermaltake 630W Smart: 45A @ 540W (4th tier).

If you plan on overclocking or crossfiring then you should get the strongest PSU possible. Remember that a 500W PSU really isn't actually 500W... it's slightly lower. The first PSU I ever bought was 550W... and when I decided to build my first system, instead of keeping that 550W unit I opted to get an 800W unit instead because I knew it would come in handy at some point in the future, especially if I wanted to run two cards in my computer and I didn't want to go through the trouble of replacing my PSU.

really should get a better psu
