7800GTX got ppl letting go at RM350 only? If i'm using PCI-E might consider to SLI the 7800GTX also. 7800GTX SLI,my dream machine card...

Use the software from your card vendor or RivaTuner.What series of card are you using?

As long as not going too far from the limit the overclock will be safe.Most of our members here also doing overclocking on the CPU,RAM and display cards.

Nowadays playing games need at least 512MB to support,if you have more the better is. Then only consider to get better GC for gaming,else got no "ohm.." one.

Depends on the game you play,i suggest 512MB RAM for those 3D games.I think should be common right now.Else what's your suggestion ?

I'm playing C&C 3 with my P4 using 1GB RAM.For me i think is still ok.I got the playablr frame rate at 30FPS with my 9550.

Game software crash with the GC hardware?Or got overheated?Maybe you can firstly check you Centrino core is running hot or not in gaming.

I guess notebook will be running hot while playing games.Maybe you will need other notebook cooler to cool down the proc and memory area. My Dell notebook is also hot when on loading....yet i'm not playing games also.

You can try on this... Between we are a bit out from topic already.

Inno brand card looks promising or not?Because they are very few people using this brand.Sounds like Galaxy and XFX is better...What about the Leadtek 7600GT?

Sempron 2800+ is running below 2GHz right?But i think not your system's problem.Does your CPU overheat while gaming?

OH,like that.Do you feel your CPU suddenly slow down during gaming?MAybe earlier time the game is smooth,but until certain time then become lag?Or yours is feeling lag in the beginning of the game?

I think there is something to relate with your CPU as your display card and RAM is preety enough and good for your system.What vincent said are correct,they are the natural behaviour of the products.
