what is bottlenecking ? and which graphic card should i buy to avoid it.

ANKUSH MISHRA · Oct 12, 2014

my pc confid:
amd fx6300
gigabyte 78-lmt-usb3.0
corsiar 450w
4gb vengeance

That would go well with a R9 270 from AMD or GTX660 from Nvidia. If you have 64bit OS then the ram would be better as 2 x 4GB, 4GB would be the bottleneck.

Go for a amd r7 265 . Budget friendly gpu. Bottlenecking is where you do not get full performance from a gpu or what ever- e.g. A intel pentium at 3.4ghz with a titan Z. U will be bottlenecking like a motherfucker.

To answer the first part of your question. "What is Bottlenecking?"

Bottlenecking is a slow down that occurs NOT because of a processors in-ability to process data quick enough. Instead, bottlenecking is the in-ability of the Bus Paths in your system to transfer all the data that your processors CAN compute.

Imagine this... You need to fill up your swimming pool. You have all the water required to accomplish this, however... The only hose you have is a McDonalds soda straw... It's going to take a while to get that water through the straw. Would be quicker if you had a garden hose, or better yet a fire hose.

So... To avoid bottlenecks, you simply want to make sure that the bus paths on your motherboard are capable of handling the traffic that your processors are going to be throwing at it.

For example, if you put a PCI-E X16 video card into an X8 slot... Or more commonly, it's easy to buy two video cards for SLI/Crossfire only to find out that the two PCI-E slots on your motherboard are two different speeds. (1 is x16 and one is x8)

Hope this helps.

so which one will you prefer as a graphic card?

ANKUSH MISHRA · Oct 24, 2014

can you review or suggest/ compare sapphire R7 240 1GB DDR5 AMD/ATI radeon with galaxy NVIDIA getforce GT 730 GC 1 GB DDR5

You've limited yourself with that PSU, but anything below a r9 270X, i had a 7870XT which is similar and I was bottlenecking on badly optimised games with a FX4300

rolli59 · Oct 24, 2014

ANKUSH MISHRA :

Both are entry level cards with the GT730 having the edge. If you can go R7 250 or 250X you get a better card.

Linustechtips just rips the R7 240 to shreds in this video:

Those framerates look awful. Maybe it's capable if you're only gaming in 720p?

R9 270 recommends 500W power, I think. Don't know whether your PSU is good enough to disregard that. But here is a very good deal at $109 after rebate for a GTX 750Ti, which only recommends a 300W PSU.

This card will play Crysis 3 on high at a smooth locked 30 FPS with an overclocked Pentium G3258. I'd imagine your CPU might be a more capable processor for a multithreaded game like Crysis 3, but don't take that to the bank as I don't know AMD processors that well.

Here they show very smooth mostly 60 FPS play on Battlefield 4 using a 750Ti at 1600x900 and high settings. I think the CPU is an i5 or an i7 though.

If your power supply can run an R9 270 or R9 270x you'd be better off with them (plus with three free games), but the GTX 750Ti seems like a very capable GPU for the price.

HomerThompson · Oct 24, 2014

If you do want an R9 270, newegg has a shell shocker deal for today only for one for $130 after rebate

rolli59 · Oct 24, 2014

R9 270 recommended 450watts http://www.realhardtechx.com/index_archivos/Page362.htm

HomerThompson · Oct 24, 2014

rolli59 :

Are those recommendations for continuous power? Or do they mean buy crap brand X's 450 Watts max rated power supply and that should be enough? The R9 270 I linked says it uses 150W.

rolli59 · Oct 24, 2014

HomerThompson :

Recommendations are always high because of all the generic crap that is on the market real total system load with a single R9 270X here is less than 300watts http://www.anandtech.com/show/7503/the-amd-radeon-r9-270x-270-review-feat-asus-his/16

ANKUSH MISHRA :

That is a difficult question to answer. But I'll try.

The most important thing you want to make sure of, is not to bottleneck the thing... Make sure the card you buy is "PCI-E 3.0 x16". AND Make sure the slot on your motherboard where you'll be plugging the card in, is also x16. It needs to have 16 lanes on the PCI bus.

If you're going to use two cards, make sure both cards are PCI-E 3.0 x16, and both slots are x16.

As far as Which particular card to buy... That's more a question of how much $$ you want to spend. I could tell ya the best card to get is a GeForce Titan. But it's AT LEAST $1,000. lol

Just make sure the card is PCI-E 3.0 x16.

-----------------------

Nvidia? or AMD Radeon????

Either Choice is fine. I prefer Nvidia cards personally. Nvidia cards seem to handle a few more post-processing effects before they drop fps. On the other hand, they are about 20-40% more expensive than AMD cards...

Radeons perform great too. Stunning graphics, high fps, and they're cheap.

Just make sure it's PCI-E 3.0 x16... Along with the slot on the MB it will call home.

OP has already stated that he has AM3+ system which does not support PCIe ver 3.0 only 2.0. Really does not matter since none of the cards in question can saturate the ver 2.0 slot at X16!

Witt · Oct 25, 2014

rolli59 :

Yeah. If you compare two equivalent cards, Nvidia VS Radeon... Typically, they are within 3-5% of each other in performance. (Which is really not even noticeable unless you have two identical PCs side by side.)

There are two main differences I see between Nvidia and Radeon.

1 - The Nvidia card is going to get me one extra notch on the Ambient Occlusion slider, before my FPS crash.

2 - The Nvidia card is going to cost me $20 to $80 more than the Radeon equivalent.

I prefer Nvidia, but have used both. TRUST ME.... There's nothing wrong with a Radeon.

rolli59 :

/bonk

Thanks for the heads up. Looks to me like the OP needs a new Motherboard. :wahoo:

rolli59 · Oct 25, 2014

Not really like anybody else on AM3+ FX system http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/23.html

Carl Blance · Oct 27, 2014

Well it is enough but if your like me and dont want to hear noise from your psu cause the load well...

what is bottlenecking ? and which graphic card should i buy to avoid it.
