The 6470m is a pretty bad video card if you are thinking about gaming on your laptop. The memory upgrade won't help either for gaming. But if I had to choose between the two, I would go with the GPU upgrade.
Thanks for your input. ^^
Yea, I'm thinking about some gaming but not hardcore gaming like crysis and cod. I will be playing games like Vindictus and Dragon Nest from Nexon though. If only dell had a better graphics card upgrade.... ugh.
Any other suggestions are still welcome to post. I'm not 100% sure to upgrade yet.
