Upgrading my Dell 8300

So supposedly I was gonna build a new rig, but couldn't get enough $$ for a new one. So i'm hoping to get some 2nd opinion on how to upgrade in my current rig. I have an almost 3yr. old Dell 8300(YES I KNOW. DON'T LAUGH) and my current plan is to upgrade the GPU and PSU.

I have read that Dell 8300 not working with some GPU so I was wondering if anyone has tried putting a 780 on their Dell 8300 and worked. if yes, what brand did you get?

Motherboard: Dell Inc. 0Y2MRG A00
CPU: i5 2320 @3.0
RAM: 8gb
GPU: GT 545
HDD: 1tb
PSU: 460w

UPGRADE:

GPU: GTX 780
PSU: 650w-750w

I've talked to Overclocker support and asked for advice if my GPU will be bottlenecked by the CPU and they said it won't. I measured the dimensions in my dell 8300 and I think the current 780 and PSU will fit, not too sure though. any advice would be helpful.

and no, I WON'T(and CAN'T) wait for the 800 series. :D
 
Seems reasonably sensible, although the PSU will be over-kill for what you need, I think (I don't know the 780's power draw off the top of my head). I'd double check, but 450W should be enough to run your system even with an uprated GPU.

Then you can put the PSU money into an SSD (which will improve load times but not really game performance) or your back pocket.
 
Oh dear... Well to tidy up a little, a 450W PSU may indeed be powerful enough for a 780 and the rest of your system, however I doubt the Dell PSU will have enough power on the +12v for that or enough power connectors.

Suggesting getting a 580 is all very well and good, but not good advice if the OP wants more performance than a 580 can offer.

The CPU in your system may be a slight bottleneck to the 780 in some games but it shouldn't be too bad in most cases.

So ultimately there isn't anything wrong with your plan. But for the PSU I'd look at something like a 550W SuperFlower Golden Green. :)

Airflow to the GPU is a potential concern, OEM chassis' don't tend to have masses of airflow so the temperatures may get a little toasty.

I did. the thread was in page 3 when I updated it.

The recommended PSU is 600w according to geforce.com, can't hurt to get 750w.

Just get a cheap 580 and a ssd

nah, as a human, it is in my instinct to buy newer models. thanks for the tip though. :)

It depends how good the PSU is and how much of the wattage is on the +12v (the power rail which is used by the core components, CPU, GPU's etc). NVIDIA have to be careful with PSU recomendations because if they say 550W is enough (which it would be with a nice SuperFlower, Corsair, Silverstone etc) there will always be the guy who buys a £12.99 '550W' PSU from a high street store, blows up his PC and blames NVIDIA.

Lower end PSU manufacturers are cheeky with their naming and use the total power output to rate the PSU rather than the 12v output. I had a '700W' PSU before which only had 530W on the +12v rail, but the sum of all rails was around 700W. My current 750W PSU has 744W on the +12v rail.

I have a 750W 80+ Silver PSU and I ran a GTX780 and a GTX670 both heavily overclocked and at 100% load with it for a while. :)

Certainly can't hurt to get a 750W but getting a 550W *might* save you a little cash. :)
 
***IMPORTANT***

Some vendor motherboards (Dell being one of them) have been known to use non-standard ATX power connectors. You can potentially fry the board with a standard ATX PSU. Check to ensure that the board uses standard wiring.
