Very low FPS @ 1080p (RAM, GPU or CPU)

My setup is:
Nvidia 8800GTS 320MB overclocked to 600/1400/850
AMD Athlon 64 X2 4000+
1GB DDR2 5300 (333 MHz ram)


I have also already a AMD Phenom X4 940 black edition (waiting for thermal paste for installation), which i figured would be a v.good upgrade over current processor

Currently, most games at 720p at 1080p give quite low or VERY low FPS, and I have already guessed this is because of 1GB ram, but it could be other factors which are the bottleneck

Any Advice on RAM upgrades (idk what type of RAM is best) / is my GPU absolutely fine to play something like Assassin's Creed at 1080p??

Thanks for any advice that can be given :D

With the CPU upgrade alone you should see a lot of FPS'es increased. The RAM issue is also a big factor; try putting like 3GB or something in there.

The 8800GTS still kicks around, but maybe 1080p might be a lil' too much for 320MB of VRAM.

Cheers!

EDIT: DDR2-800Mhz would be nice, but if you can't get 'em, go for 666Mhz and more quantity.

The 8800 GTS 320 version and the 640 versions had worse performance than a 8800 gt in most games, the 512 mb edition was the one that fixed all of those problems. So the graphics card and processor could be the bottlenecks. Also the ram add one - two more gig and you should be good for 32 bit windows

Well, CPUID is giving me that reading for my RAM clock speed but it is slightly confusing as my RAM is corsair xms2 6400, and I don't even think that it is possible to get that version of ram at 333MHz clock speed. Is it possibly giving me the incorrect value?

Thanks for the reply, a stick of RAM for £25 or so won't break the bank

Because its DDR memory, its clock speed is 333MHz but its transfer rate is 667MHz so thats a valid number for the RAM.

One major limit for your system at 1920x1080 is the small amount of graphics ram, at about 1920x1080 1GB cards show a slight advantage over 512MB cards, the 320MB will be limiting you a fair amount at that resolution especially if you attempt to turn on AA at all.

I would not invest more money into a 5 yr old rig; the video card is slow, as is the CPU, and it would seem pointless buying more expensive and outdated DDR2 memory for it now. ANything beyond Quake 4/F.E.A.R/MOHAA, and you will be reminded constantly that it is probably best to be pricing a whole new rig.

If it reads 333mhz then it's probably at 666mhz - double data rate. Just like mine shows as 800mhz and it's 1600mhz.

As mentioned you should definitely go for 3-4gbs if you can. Easiest thing is a 4gb pack for around $50.

Then, depending on the motherboard a much better CPU would be maybe $100-150.

But at the least get another 1gb stick for sure.

CPU and memory don't care about resolution. If you lose FPS going from 720p to 1080p, then it's your GPU.

8800 GTS 320MB can't handle 1920x1080. If you want to game at modern resolutions, you'll need modern hardware. I couldn't stand the fps I got with the Athlon x2 5000+.

Give us a budget and we'll help with an upgrade. There's a chance your mobo is compatible with a Phenom II x4 955BE, which was seen online for $105 a week or two back. Pair that with a $140 5850 and your system will be awesome again.

Sorry, but this is nonsense. He's looking for decent gaming at 1080p, not folding at home, not intensive video editing, not a three monitor eyefinity setup, not 3D. He's already got a Phenom 940 which is a huge leap forward once he installs it. Investing 60 dollars to get 4 gigs of ram and another 150 for a New GPU (gtx 460 or 6850) if he goes that way is far cheaper than building a new rig and it will run almost every game that exits just as well as the latest i7 or i5 will the same 150 dollar graphics card.

just get more ram and another GPU.

To the OP:

This is what I'd do in order of priority (if you need to stretch the upgrade out over a couple of weeks as money comes in).

1. Stick that 940 in if it's compatible with your Mobo. It's a huge jump over an Athlon 4200.

2. Get more RAM. 4 gigs, even in DDR2 shouldn't cost much, especially if you've got 4 banks (4 1gig chips won't set you back much.)

3. Upgrade the 8800GTS. It's not really going to cut it at 1080p. Too little RAM. Too slow. It's more for when 1024x768 was a standard. The minimum you want is a GTX 460 (768). They can be had cheap, under 130 dollars and are a huge step forward from the 8800GTS. If you can spend a little more go for an HD6850 (runs cooler, uses less electricity, has 1 gig of Ram, and generally has better build quality than the 460 cards--they also overclock to near 6870 speeds with no problem).

1. Oh, yeah the Phenom II 940 you already own could be great. Make sure to upgrade to your latest bios before swapping CPUs. You don't need thermal paste to check if it posts/enters bios with the CPU. Now you do need thermal paste if you're gonna do anything, but not just for quick diagnostics if you know what you're doing (I don't use thermal paste for quick CPU swapping/checking post).

2. DDR2 is overpriced new right now. Try posting in the Classifieds Section of Tom's Forums looking for some. I might have a 533MHz (PC4200) 1GB stick I could send you. Although technically, it doesn't belong to me, so that's kind of a last resort.

3. If your 940 works, upgrade the 8800. You'll notice a big boost with just the 8800 with a new CPU. I got a new GTX 460 768MB after a bunch of cashbacks & rebates for $69 in March. I posted the deal in the Hot Deals section. The Sapphire GTX 460 768MB I got OC's like a beast though. It beats a stock GTX 470. If you're interested in used, try our Classfieds section.

4. What PSU do you have? Keep in mind that if you get a good PSU now, you can use it in a new build in a couple years.
