What should I be upgrading for my computer for better SCII performance

Here are my specs:
Windows Vista Home Premium
AMD Athlon 64 X2 Dual Core Processor 6000+ (2CPUs), 3.0GHz
2GB RAM
NVIDIA GeForce 7900 GS
1680x1050 (32bit) display

Currently I am lagging at the start of an online match when I pull my SCVs. I also lag when I alt-tab and the recommended settings are low-medium.

I was wondering what I should upgrade to stop the lag and have preferably high-ultra graphics with a budget of <$200.

Should I be upgrading my CPU or graphics card? I heard that CPU is more important and vice versa in terms of playing SCII at high settings.

your CPU is ok for SCII, your graphics card can use an upgrade. look at the ATI 5750 or 5770. both are power efficient and should run on your PSU if you can power the 7900GS. the 5770 is the better card of the two.

Ah ok, now should I get 512mb or 1GB which one and is there a notable difference between the two.

I'd say that ct1615 is exactly right. At 1680x1050 the 7900GS is pretty old for more modern graphics. It's due for replacement.

The Athlon X2 6000+ is fairly aged as well, but for SCII it should be okay.

Is your Windows Vista 32bit or 64bit? If it's 64bit, I'd also suggest finding some cheap RAM and doubling your system memory up to 4GB. That and the upgraded graphics card should not only improve game performance, but alt-tab'ing should be a bit smoother as well!

For the ATI 5770, you might as well get the 1GB. The 512mb cards out these days are usually old school cards, or designed to be "budget" minded options. The 1GB would definitely help with higher resolutions, or higher texture settings (higher detail settings).

In the <$200 price range, the ATI 5770 should work very well at your resolution. If you wanted the best possible performance for your money, the GTX 460 would be up at the top end of your budget. However, it's not necessary, and could potentially be limited by your CPU in some situations.

Unless you intend to do other upgrades, or play more intensive games (from a graphics standpoint) the ATI 5770 should be your best over all value.

What about RAM, would that be affecting me because when I play my memory shoots up to 70%-80%, my friend told me I need a RAM upgrade?

The 7900GS is a dog. I remember some 6800GS cards you could unlock some of the pipes if you were lucky, but at this stage a 7900 is so far behind, the only option is an upgrade.

You will have to do the hard work and figure out what cards will be compatible with your mobo, but i like the current 5000 series ati cards, just depends on how much you can spend.

2GB is fine for Vista 32bit

Hello, new member and a lay man in term of computer here.

Since we're on topic about SCII, i was wondering how would cards like ATI HD 4550/4650/5570 perform in SCII medium graphic setting?

Thank you in advance

this link should answer your questions about the 5570. the 4650 would obviously be a step below and i would avoid the 4550. The ATI 4550 is not designed to be a modern gaming card.

the 4550 was more like an htpc option than a modern gaming card.

Think ct1615 made a typo. He says to "avoid" the 4550. I think he meant to say "is not designed".
