Getting a new GPU, Bottleneck issues

Hetzlol · Apr 20, 2014

Hey guys, I'd like to start an upgrade for my rig which is super ancient by now :
Q8300 @ 3.2ghz
HD5750
4gb Ram
600w Corsair PSU

I've been playing very low demanding games for the last few years (CS, Dota etc) but I feel like it's time for an upgrade.

I decided to make it gradually rather than buying everything at once by starting from the GPU and from the information I gathered I think the R9 270x from ATI or GTX 660 from Nvidia are both valid alternatives to my really tired 5750 hamster.

Now I know those mid-range cards are gonna be bottleneck'd anyway but personally I'm afraid of buying a whole new system without the gpu because I feel the bottleneck will be worst then.

What do you think? Should I go the other way around?

What's the budget?

If you have the money, buy a whole new pc.
It's not really worth it to upgrade such an old pc.

Give your old psu a good cleanout and it should be good to go for a little while longer. When you are upgrading or building a pc you start with the motherboard, as this is the platform that everything will be running off.

If you where to get a new gpu then your cpu will bottleneck it, and vice versa, 4gb ram is enough to run most games (mostly just CoD Ghosts that require 6gb+ to run).

So, you can buy the parts little by little, but theres really not much use of trying to get them so you can use them a.s.a.p.

Motherboard -> cpu + aftermarket cooler -> gpu (get the parts in this order).

When you have these 3 parts (+ cpu cooler if you want it) you can clear out your case and install the new parts, then just use your old psu, ram and HDD uintill you have the money for new parts. This would be the quickest way to get a "new" rig up and running without any serious bottlenecks.

200€ Right now, I'm planning to get a new pc, just don't have the money at the moment.
I planned to buy a good gpu so while gaining a bit of performance, I'm good for when I upgrade the rest..

So you say that I will benefit more from upgrading the motherboard-cpu-ram and let my current gpu bottleneck it? It's a matter of chosing what to get bottlenecked from (it sounds weird I know) until I have the money to buy the rest of components.

No, i said to buy the hardware in this order:

1st: motherboard
2nd: cpu
3rd: gpu

When you have these 3 parts, then you can empty your case and install everything using the new motherboard, cpu and gpu + the old psu, ram and hdd.

Then later you can pick up new / more ram, a new psu if its starting to get really old and an SSD would be recommended for the OS atleast.

Unless you are using an APU (motherboard intigrated graphics, then the ram has very little to say when it commes to game perfomance).

The HDD speed will only matter when it commes to how fast your loading screen will be and just make sure that the PSU delivers enough AMP on the 12v rails to power the new gpu. I am guessing that you have a Corsair CX600 psu, so for a R9 270x it should be good to go.
