Specs: Windows 7 Ultimate 32bit, DualCore Intel Pentium D 830, 3000 MHz (15 x 200) / 4Gb Kingston DDR2-800 DDR2 SDRAM
Hi guys, wondering if someone can help me please. I need to find my "bottle necking" hardware so i know what to upgrade. After buying the Palit Sonic Platinum GeForce GTX 460 Video Card I thought I would be able to play anything on max with great FPS. However, when I am playing a game (e.g. CS: Source, Starcraft 2, Alien Swarm) and there is a moderate amount of action there will be slight lagg and it wont run as smoothly as i'd like it to. Whether I have the grfx settings on Ultra or Medium there is always this same type of lagg or slowness when there's explosions / shooting etc. This leads me to think it may be my cpu / ram / mobo or maybe all? Here's my list of hardware. Any help much appreciated.

Case: Antec 1200
PSU: Antec 850w
Mobo: Asus P5N-D nVIDIA nForce 750i SLI
CPU: DualCore Intel Pentium D 830, 3000 MHz (15 x 200) FSB 200.0 MHz
RAM: Kingston 4x1 GB DDR2-800 DDR2 SDRAM (5-5-5-18 @ 400 MHz) (4-4-4-12 @ 266 MHz) (3-3-3-9 @ 200 MHz)
Graphics: NVIDIA GeForce GTX 460 Sonic Platinum(1024 MB)
HDDs: (250 GB, 7200 RPM, SATA), (Samsung F1 1000 GB, 7200 RPM, SATA)
OS: Microsoft Windows 7 Ultimate

Bottleneck is the CPU - crappy P4 technology. Shop for a Core 2 Duo.

So what is the difference between the pentium D and the core 2 duo?

Can you recomend the best core 2 duo to get?
What is the main thing am I looking for when buying a new cpu? Clock speed? FSB?

Do you think buying the core 2 duo will get rid of this lag I am experiencing?

If I want it to run perfect and score very high in benchmarks would it be worth changing the mobo and getting... for example the i7 Core? or similar?

The Pentium D is based on the P4 which uses the crappy inefficient netburst technology. The Core 2 Duo is based on the new Core technology which is loosely derived from the much more efficient P3 platform. The benchmarks don't lie:

Your board doesn't support the Core i3/i5/i7'd need a new board & new RAM for that, not to mention the CPU, so you'd be talking a fair amount of change if you were to go that route.

I suggest you either get a Core 2 Duo E7500/2.93GHz/1066MHz CPU for about $125 or you could even get a Pentium Dual-Core E6500/2.93GHz/1066MHz for about $80. The Pentium Dual is basically a Core 2 Duo but with less L2 cache. Your board supports both but you *may* need to update the BIOS.

Your board also officially supports 1333MHz FSB (& probably higher). Both these CPUs clock in at 11 x 266MHz & have downward-unlocked multipliers so you could easily reclock them to something like 9 x 333MHz (3.0GHz) @ 1333MHz FSB & adjust your RAM to run at 667MHz to be in sync. And if you're into overclocking, you should have no problem at 3.33GHz (10 x 333MHz).

How much unnecessary software do you have running in the background?

Now that's what I call a sticky situation

Just formatted and have absolutely nothing running at all in the background. Just the game.
Thanks anyway though.


Thanks for your help.
So I think I will leave the i7 etc.
I dont mind spending the extra cash on the cpu so long as i can get the most out of my graphics card.
I found the Intel Core 2 Quad Q6600 Energy Efficient 95W edition Socket 775 (2.40GHz) G0 Stepping L2 8MB Cache OEM Processor on ebuyer.
I checked and my MoBo can support it. Its about $270 but i dont mind that knowing i will be getting the best.
Do you think this is a good idea? If not, you have any suggestions? I like the sound of 4 cores haha
