I'm planning to buy an Intel Core 2 Quad Q8400, so I can play Black Ops without any stuttering. But right now, I have 9500 GT... I realize there is goign to be a bottleneck. Can someone tell me HOW MUCH bottleneck there will be if i keep my 9500 GT. also, can anyone recommend me a gpu that won't bottleneck the Q8400? please, don't just tell me the name of the newest gpu. i want to save money AND enjoy the game.

5770 is often the minimum recommended gaming card, but, I personally prefer something at least as powerful as the GTX460(1gb), but, prices fluctuate...

GTX560 is also a good card, as is the 5850 or 6850...

The 9500GT is considered 'ancient' with today's games/these days...

I plan on upgrading my GPU from a GeForce 8800 GTS 640mb to a GTX 570 but my tower is at least 3 years old and I don't even know if the 570 will be able to run at its full potential. Here are my current system specs:

Motherboard: ASUS M2N32-SLI Premium Vista Edition AM2 NVIDIA nForce 590 SLI MCP ATX AMD Motherboard
Power Supply: Antec - 850W True Power Quattro PSU
OS: Windows 7 (64 bit Edition)
RAM: 4 x 2GB Corsair XMS DDR2 800mhz 240-Pin SDRAM
CPU: Athlon X2 6400+ Dual Core Processor (3.2GHz)
GPU: EVGA 640-P2-N824-AR GeForce 8800 GTS 640MB 320-bit GDDR3 PCI Express x16
HDD: Western Digital Caviar Blue WD5000AAKS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive

I just wana know how high I can go in terms of GPU without running into bottlenecking. I dont know if theres a specific ratio of CPU/GPU clock speed or anything like that, I just wana get the best card possible that wont be slowed down by my CPU...

Athlon X2s are slower than Phenoms, and any DDR2 based rigs are somehwat slower yet, so to a certain degree, you might always be suffering 20-30% lower framerates than might be possible with i5/i7 rigs, but, the higher the resolution, the less impact the cpu has....

I'd be planning my next rig no later than this fall after BD release/evaluation of gaming performance....

erol, you will use 10% of that GPU with that CPU, so it's a waste of money
OP: i had a Q8200 *or 8300 can't remember :p * paired with a 9500GT and i had 0 bottleneck, you can only be bottlenecked when your CPU is too slow for GPU.

my current CPU is "Intel Pentium D 2.8 GHz dual core"
my current GPU is "Nvidia GeForce 9500 GT"
I play Black Ops on an average fps of 30. I'm thinking about upgrading my CPU to "Intel Core 2 Quad Q8400" and keep my "9500 GT" if I can. So, you're saying even if my GPU will be slower than the CPU, there will be no bottleneck? Will my fps go UP or DOWN if I ONLY upgrade my cpu to Q8400??

No but it wont improve on the margin by much either... if your thinking of upgrading the LGA 775 platform is dying off... buying the quad will certainly help your graphics measure up to the maximum performance but keeping in mind that you'd have to upgrade you graphic card very soon and any LGA 775 platform processor would seem to bottle neck any new graphic card by quiet a margin...

well, I'll be stuck with this motherboard and computer for another 3 years so I'll have to deal with it. so you're saying it's not going to improve much if i only upgrade my CPU? what GPU do u recommend to go along with it? and plz dont recommend an expensive one.. just enough to have no bottleneck.

and why did shrkbay say theres no bottleneck if its the GPU thats worse?

l
July 12, 2011 5:28:32 PM

What shrkbay means that if you get the Quad Q8400 is a little too powerful to bottle neck the GT 9500 if your Pentium wasn't creating a bottle neck for your GPU... if the Pentium was able to match the performance of the GT 9500 then the Quad will over perform the Graphic card... hence there wont be much difference in the graphics...

If your looking for the cheapest graphic card for that processor consider the anything between the HD 5770 to HD 6850... Personally I think the GTX 470 outperforms all other cards with that processor at stock speeds without any bottle neck...

^ I would not risk to pair GTX470 with C2Q and probably an old PSU, 470 will draw too much power causing system death. Anyway imo best cards to pair C2Q with are *starting from the fastest* HD6850, GTX460, HD5830, HD5770, GTS450, HD5750 and lower *mostly low profile HTPC cards*

yes, shrkbay. my psu is 500 watts and I believe GTX 460 requires minimum of 450. so should I first upgrade ONLY my cpu and see if theres any bottleneck. then upgrade to a GTX 460? also, how do i know if there is a bottleneck with my CURRENT setup?

There won't be any bottleneck when C2Q is paired with 9500GT, but you will get A LOT more from GTX460 or any other card i listed, but GTX460 is better with 550W PSU. Check how many FPS you get normally and then check it when your CPU is overclocked, if you see an increase means you are bottlenecked. What's your PSU model? Or if you can look how many A's it has on 12V rail.

so i will get an IMPROVED performance from only upgrading my CPU? I will try that first to save money, then if it IS necessary, i will upgrade to a GTX 460. i heard it needs 2-6 pin connectors and its dual slot. ill have to check if my motherboard has a place for a dual slot card.

my psu model is Rocketfish 500 Watt. on the box, it says 600 Watt peak. does that mean it can go up to 600 watt?. also, what if I don't have a 6-pin connector? will the card not work AT ALL?

I'm not sure wat u mean by "how many A's it has on 12V rail" so I'll just write the whole thing on the box

Input Voltage : 100-240V, 50-60Hz, 10.0A/5.0A
Output Voltage : +12V1DC +12V2DC +5VDC +3.3VDC -12VDC +5Vsb
Max Load : 18.0A 18.0A 18.0A 18.0A 0.3A 2.5A
Min Load : 1.0A 1.0A 0.5A 0.5A 0.0A 0.0A
Max Watt : 432W 130W 3.6W 15W
Rated Watt : 500W

do i have a 6-pin connector?

6 x SATA connectors, 7 x Peripheral connecotrs, 4+4 CPU connector,
2 x PCI-E connectors (8-pin, but it's actually a 6-pin with another 2-pin)

your cpu sucks what do you expect, you can throw an am3 build together quite cheap these days and I would not waste a dime on buying a new cpu for the dying lga775 platform, Furthermore your gpu is crap>>>>>>>> time for a new build or to lower your expectations ; your cpu, and gpu are ancient, and your power supply is just plain sketch, all of them need to be replaced and in reality your motherboard and RAM as well, otherwise you might as well stick to SNES emulators and diablo II.

IMO I wouldn't upgrade to a C2Q given how they're just as expensive as i5/i7s. Maybe just go with a fast dual core, something over 3ghz. You will not see much FPS increase going from your current CPU to the quad, except maybe in a few highly CPU dependant games. Overall though the 9500GT is going to be the "bottleneck" aka it's the slowest part, although that does definitely depend on your resolution and what games you play.

I haven't seen anything about what resolution your monitor is but I would recommend at the least a 5770 for gaming, if not a 460, 560, or 6850 (or higher).

So basically I think the best course of action right now is
1) buy decent PSU (~$100 500W+ like a Corsair, Antec, Seasonic...)
2) buy decent GPU (~$100-200)
4) save up ~$300-$400 and get a new i5 2500k, Z68 mobo, and 8 gigs DDR3 (Or wait a little longer for AMD's new CPUs to be out and maybe go with that, depending on price/performance)
5) consider a new case (<$100) and a new fast HDD (<$100) or SSD (~$200)

Why does no one factor in resolution/# of monitors into these questions?

The power of the GPU that you need is determined by the resolution you play with or number of monitors or if you plan to used 3D, not your CPU.

The CPU is only a bottleneck in one of 2 situations; 1) it's just not powerful enough for the games you play, due to being old, 2) or because you have too powerful of a GPU setup for your resolution, which really is bogus. The CPU isn't a bottleneck, the GPU is just too powerful.

Sure it does.

Let's say he buys a 460. By the way many people here would consider a "bottleneck", a gtx 460 would be bottlenecked by his CPU if playing at 1024x768, but it would not be bottlenecked by his CPU if he played at 1080p.

Also I run all my games at 1920x1080 with at least 4x AA and 16x ASF. The only games I have to turn them off is Crysis II and Metro 2033. No matter what I always leave my resolution at 1920x1080. Im not worried about a slight bottleneck but i know that I wont get a 90% bottleneck with my setup.

to the ppl who keeps telling me to get a new mb and replace everything. i'm ONLY trying to replace my cpu. and maybe the gpu if needed. so are you guys saying i should get a dual core cpu with a high GHz rather than the Q8400? i heard new games will utilize multicores so quad core is better.
i play black ops, fifa 11, company of heroes, and WILL play mw3 when it comes out.

He gave you blatant and truthful advice, HE TOOK HIS TIME TO HELP YOU. Though he could have worded it better, you are still not in a position to be rude.

Changing MB or build a new PC is really the best thing you can do. Anything you can get on the socket 775 is completely obsolete and weak. The quad core won't stand up well against newer Dual cores at all. Say if a newer dual core is 100%, 50% per core, a older quad core will have only 20% per core, giving 80% total, making it still weaker.

The 775 is a completely dead platform, and the 775 Quads are getting antique values to make the ridiculously expensive. The best way of deciding whether to change MB or not is your budget. What is your budget? if you have more than $150 to spend on CPU, then changing MB is the way to go.
Peace.

szbxa. Hi, thx for responding. In a simple attempt to play Black Ops with a decent fps, I have reached the point where I have to pretty much buy a new computer. As you've asked, my budget is about $300. However, I'm not a computer expert, so I have no idea how to change my motherboard, nor am I a gamer who demands the best quality.
Due to my monitor, I think, 1024 x 768 is the highest resolution I can play without the game window distorting or not fitting in perfectly to the screen. I have a 500 Watt psu and the descriptions are above. My case is Dell Dimension E520.

The hardware recommendations I've been getting are for high-end gamers on my opinion. I'm aware that LGA 775 is the ****tiest socket type there is, and I wish I had a motherboard with a better socket type. But being a computer noob, all these changes seem daunting. Especially the amount of money I'll have to save and spend just to play with average quality and decent fps.
Is there ANYWAY I can play with at least 60 fps and 1024x768/high quality settings on Black Ops and more games to come within the next few years without replacing the WHOLE computer? If not, please write an organized list of hardwares that I will need to purchase to make the "rig" I(?) (or for the standards of high demanding gamers) want. Apparently, I won't be making any purchases in the next few weeks, so I'll have time to save money.

P.S. : If it is possible, please recommend cost-efficient hardwares that won't rip me off..... please.... I already spend about $300 in the past few years to make my **** comp a little better, only to end up as a **** comp again.

The i3 2100 sandybridge is better than Q9550 at gaming. The reason why I picked i3 2100 over the 955 is because your major usage is gaming, and because it takes less power than the 955. (I don't trust the Dell PSU)

The Zotac AMP! edition of GTS 450. At 1024x768, it'll probably handle even Crysis on highest details.

There you go, $287 plus shipping plus tax makes a $300. Definitely plays Black ops on highest with 60~ fps.

DON'T SINK ANY MORE MONEY INTO USELESS PARTS LIKE Q8400.
the 30~fps you have should be coming from the 9500GT, your current PC is balanced with the CPU somewhat bigger than the videocard which is an ideal situation. Upgrading your CPU will not inprove your FPS, and upgrading videocard along will get you bottlenecked.

As for the RAM problem, you always have the option of pirating OS, it's fast, simple, free and 100% same as the genuine version (updatable), you can easily switch over to win7 Ultimate 64bit. YOU SHOULD NOT PIRATE, you have the hardware, so why not?

You pay the cash first, the other guy shouldn't hesitate too much. Or give him a $5 bonus or something.

Ok you have a very low res monitor then, apparently (although if you can set higher resolutions but it's "distorted" then I'd suggest you try to find the drivers for you monitor). Anyway at that res a 5770 is fine and don't bother upgrading the CPU right now. A 5770 should be under $100, although if you can find a 460 at that price then it's a good deal (it's slightly faster but ultimately even a 5770 will destroy games at your resolution). I'd then keep the $200 extra, mow a few neighbor's lawns, and at around $300 piece together a new mobo, cpu, and RAM. You might find that a daunting challenge right now but I assure you it's as easy as playing with lego. Everything has a name, a label, etc, just plug everything in properly and you're basically good to go. You'll probably want to do a fresh OS install though at that point.
